Welcome to the Open SDR Project!

What are we doing?

We're creating an open source Software Defined Radio.   To be more specific, we're designing the software and hardware to enable experimentation with the latest digital wireless protocols.

What is a Software Defined Radio?

Joe Mitoloa says, "A software radio is a radio whose channel modulation waveforms are defined in software. That is, waveforms are generated as sampled digital signals, converted from digital to analog via a wideband DAC and then possibly upconverted from IF to RF. The receiver, similarly, employs a wideband Analog to Digital Converter (ADC) that captures all of the channels of the software radio node. The receiver then extracts, downconverts and demodulates the channel waveform using software on a general purpose processor."[1]

For our purposes, on the receive side, the idea is to get a wide band ADC as close to the antenna as is convenient, get the samples into something we can program, and then grind on them in software.

What could I do with an SDR?

OK.  I'm interested, now what?
