A video of the author presenting his receiver can be found here: By providing source code, thorough documentation, easy to grasp tutorials, and a place for open discussion modern radio systems will be demystified by covering everything from the RF, analog, and digital hardware design to the firmware running on the ARM MCU and FPGA to Linux kernel device drivers.

This FPGA has single-cycle access embedded memory, hard 18×18 multipliers for dedicated DSP and many general logic elements ready to be programmed. But remember to decimate in order to gain few bits, if you want to have quite high dynamic Not bad for a low cost wide band device.

Which is good for the price! Indeed, final dynamic will not be 87 dBs due to input stages, but we should obtain pretty good results from this device anyway And you can still implement clever decimation to increase dynamic on a reduced bandwidth. Here we are, the new version is coming, and maybe already available. And probably more important for potential users: The native oversampling rate is A specific control software is used elsktor parallel to the SDR software in order to control the radio.

Bloc diagram will be found here: And full schematics here: Eleektor it is working exceptionally well under Windows platforms! Try it, and adopt it! The module can be used stand alone or plugged into other products.

Baudline is a sfr browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail.

Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters.

The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics. The aim of this project is to create a family of software defined radios SDRs for the microwave bands.

Probably the cheapest SDR setup you can imagine!!! It is written in C with both object design correctness and performance in mind. The project started as a simple proof of concept program to get hands into DSP techniques and has evolved to what it is today: A fully featured SDR capable of handling samplerates from kHz level soundcards up to multi hundred MHz dedicated samplers, thanks to its multi-core architecture.

Have a look at manual here: Characteristics and performances are very similar If not the same. The version used Nexys2 employs a 1. The board provides USB 2. This is OK for a single signal, isolated from others by physical filtering TV signal indeed! A solution is to oversample your baseband, and then decimate to increase the effective number of bits.

It is then possible, through HW modifications, to interpose 2 differental analog baseband filters in order to improve the system in addition to oversampling In conclusion, an interesting solution, close to the “funcube dongle” concept, already presented here. But the funcube has more dynamic, by design.

It is effectively an open design, so in case you want to customize the firmware of the radio for your own purpose, it is perfectly doable! As the schematic and layout for the srd is also available. Complete schematics are here: Potentially prefer an external high end one, like EMU Well, here is an other simple setup for VLF: Important point, source code available here: Research and publish the best content.

No tag on any scoop yet. SD software-defined radio receivers use a bare minimum of hardware, relying instead on their software capabilities. Sign up to comment. Your new post is loading Scooped by Christophe Fourtet. Fully bus-powered USB 3.

Noise figure and IP3 are acceptable. Output power is annouced at 6 dBm CW in the datasheet. Angilberto Muniz ‘s comment, May 7, Christophe Fourtet ‘s comment, July 25, Giacomo ‘s comment, July 14, 2: FFT spectrogram for Linux. Source code is available. The digital backend of this transceiver system, is based on: A direct sampling short-wave SDR receiver. But the biggest cherry on the cake is that source code is available for educational purpose. It is compatible with eleltor well known SDR software.

Performances are the following: A shortwave Receiver with Network Interface. As the schematic and layout for the radio is also available, it may also serve as the platform for your own integration project. It is a sum of ‘little tricks” that leads to this point of optimisation.

In addition, it is built in a small packaging. A free high performance C written FFT subroutine. A fast, free C FFT library; includes real-complex, multidimensional, and parallel transforms. Benchmarked against many other FFTs. Just a sound card and that’s it! How do I publish content on my topic?
