The computers we normally use are Windows system. The first method is to install a dual system. The second method is to install a virtual machine and install Linux in the virtual machine. Because method 2 does not require additional partitioning, changing the BIOS, etc. Therefore, method two is preferable. The common virtual machine software VMWare Workstation is used here. Ubuntu Ubuntu is a popular distribution for Linux. The downloaded file is the image.

Set the Supper User password, which is the root password. Before the user sets the password, Ubuntu will generate a random root password each time. This is different from our general cognition. The system prompts you to enter the password again, the second time you enter the password and confirm it, and the password is set successfully after two times. Next input. Update the source, you will be prompted to enter the administrator password you just set and press Enter.

After waiting for the download to complete, download and compile and install the UHD driver. If the compilation crashes in the middle the virtual machine may appear, due to insufficient memorythe re-synchronization will continue with the previous compilation progress. For the input of some long commands, you can reduce spelling errors by auto-filling, saving time and effort.

When the device is found, you can run the following procedure to view the upstream spectrum of the CDMA mobile phone.

Users may select non-default clock rates to achieve integer decimation rates or interpolations in the DSP chains. The clock rate can be set to any value between 5 MHz and Note that rates above 56 MHz are possible, but not recommended.

Note that the master clock rate must be an integer multiple of the sampling rate. If a master clock rate is chosen for which this condition does not hold, a warning will be displayed and a different sampling rate is used internally.

Nevertheless, there are multiple valid values for the master clock rate for most sampling rates. The auto clock rate selection attempts to use the largest possible clock rate as to enable as many half-band filters as possible. Expert users might have cases where a more fine-grained control over the resampling stages is required, in which case manually selecting a master clock rate might be more suitable than the automatic rate.

On the B and B mini, there is one transmit and one receive RF frontend. The receive frontends have 76 dB of available gain; and the transmit frontends have Gain settings are application specific, but it is recommended that users consider using at least half of the available gain to get reasonable dynamic range. Generally, when requesting any possible master clock rate, UHD will automatically configure the analog filters to avoid any aliasing RX or out-of-band emissions whilst letting through the cleanest possible signal.

If you, however, happen to have a very strong interferer within half the master clock rate of your RX LO frequency, you might want to reduce this analog bandwidth. UHD will not allow you to set bandwidths larger than your current master clock rate. RX LED indicators are on when sending samples to the host and off when unable to do so.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Please feel free to let me know if there's something that you know and I don't because I'm always looking to improve my understanding of the tools and techniques. If some of these methods seems strange or uninformed, this is why.

However, for those coming from the Matlab world, Octave tries to maintain itself as a drop-in replacement. The syntax is nearly identical and many Matlab scripts can be run as-is through Octave.

I've often looked at Matlab code on the Internet that helped me get my Octave code working. This is the name that my colleague gave the unexplained spikes in amplitude at the very beginning of the captures. One major difference that I've seen is the processing capability. Matlab appears to be able to process large data sets significantly more quickly and never seems to have memory issues again, from my limited experience. Octave, on the other hand, appears to have linear performance in that there is a direct correlation between the size of the data set and the amount of processing time.

The two communicate through a named pipe and I have noticed that large data sets will "make that pipe blow up" and GNU Plot will not function properly in such instances. It works by having the user hover the mouse over the plot and enter the X coordinates into the terminal and allowing each chunk to be saved individually.

If you're wanting to do a quick check of a plot, cut down on the number of samples that you're viewing on the time domain. It was very handy in being able to identify ASK modulation. Octave mirrors the Matlab functions for doing so. Practically speaking, can be used to control color "intensity". However, it plots significantly faster, doesn't require any of the downsample trickery mentioned above, and supports panning which is a huge bonus.

If you have the patience, and can stand some quirks, then I'd check it out.It is possible to have a different version of these tools, however in that case please refer to the Getting started with RFNoC website for more details. Define a jFed experiment using this example rspec file usrpx Wait for a confirmation email from testbed platform, it usually has the subject your reservation slot has started.

Category : Getting Started Guides. Navigation menu Personal tools This makes the cost of getting setup with a BBB more or less the same as that of a R-Pi but with notably better overall performance for most applications. The advantage of the latter is that during development a USB Ethernet interface can also be created, allowing command-line users a convenient way of working with the board - you get both power and network connectivity over a single USB cable.

For code relating to that project, see Documentation of GSM spoofing strategy used at Transmediale, First you need a 4Gb or more MicroSD card. Stick it into your laptop, open up a terminal and type dmesg. For this reason I will choose mmcblk0 as the device representing the MicroSD card. Now we can dd it onto the MicroSD note that I use mmcblk0 - yours may differ!

When done take it out of the laptop and plug it into the unpowered BBB. Plug in an ethernet cable connected to your Internet gateway. I like to have both laptop and ethernet cable on a switch for this next part.

Wait for the LEDs to start flashing and release. This indicate the Debian image is being flashed to the eMMC. It will take around 10 minutes and then stop flashing, with all 4 LEDs on and static.

This indicates success. Above information resourced from here. Type ifconfig -a on your laptop and you should note a new Ethernet device. Note the IP you were given. In my case it is always Now test to see if you can ping the BBB:. First, check you are online with the BBB with a simple ping criticalengineering. If not, ask for a new lease. Click on this link on your laptop and find the latest stable non-rc kernel for the BBB. In my case it is v3. Now on the BBB not on the laptop download the file using wgetpasting the link you saved above into your terminal note my URL may differ from yours :.

It should report you have a new kernel version. Once installed, type the following to clear out all the downloaded packages from the cache, recovering precious disk space:. Type dmesg and note the device in the output.

As the user debiancreate a mount point called src in the home directory of the BBB:. Now we mount it, in such a way that our user, debiancan write to the mount point:. Now go and do something entirely unrelated and come back in an hour.

Fetch and build osmo-trx. OpenBTS is the software that provides us with the software part of a cellular station. It allows us to control the transceiver, manipulate our cell station, interface with SIP for calls and SMS and all sorts of other things.

We need to edit a Makefile to represent the correct architecture. While the rest of OpenBTS is fine, the Transceiver component which we actually replace with osmo-trx is not.
