Simple Software Radio Peripheral - SSRP

1. Generalities

SSRP aims to be an alternative product to USRP. This project goal is to develop a modular hardware solution, with a radio that only convert the RF signals to baseband samples, and transfert these samples through an USB link to the host PC.

Up to now, the SSRP project is only able to process signal without RF part. Hence, the processed signal are real signals, with a maximal bandwidth close to 15MHz (since real signals are transmitted and the DAC depth is 8 bits.).

2. Main characteristics

Radio interface to computer	The SSRP is connected to a computer with a USB 2.0 interface. Because of this interface, it is limited to signals with at most 5 MHz of bandwidth.
Frequencies	No RF, SSRP only works in 0-15MHz (yet)
MIMO	Not yet
ADC/DAC	ADC: 14 bits (at 30Ms/s) - DAC: 8 bits
Baseband	The baseband processing consists in sampling the signal and performing the downconvertion.
Software	GNU Radio.
