1. What is RxCS?

RxCS is a toolbox dedicated to simulation of compressed sensing solutions in radio receivers. It consists of modules which are divided into five groups: signal generators, signal acquisition, compressed sensing processing, signal analysis and auxiliary modules. All of the modules may be used separately or with cooperation with other modules.

Go to Examples section for illustrative examples of using RxCS.

Programming language

The toolbox is written almost entirely in Python, however you may also found C language here and there.

Platform

The toolbox works well with Linux and OS X operating systems.

Prerequisites

RxCS requires Numpy and Scipy to work. It is also recommented to install Cvxopt.

License

Most of the modules in RxCS are licensed with FreeBSD license, few are published under GPL license.

Current version

Currently (March 2017) RxCS v. 2.0 is available.


2. Download and contribute:

Please download the newest version of the RxCS (zipped) directly from GitHub

You can contribute to the project using GitHub. Please go to the project’s website:


3. What is inside? Directory structure

The first two levels of the directory structure of RxCS are shown in image below. All the RxCS modules are hidden in rxcs\ subdirectory, which has four subdirectories with fours basic groups of modules.
