The topic is GNU Radio and Python.
GNU Radio is a free software implementation of Software Defined Radio.
"Imagine if the only thing stopping your handheld PDA from simultaneously being a GPS receiver, phone, radio or miniature TV was your willingness to download and install some free software program."
"We're pretty much turning all hardware problems into software problems," Blossom says. "We want to facilitate evolution in the radio arena."
"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."
GNU Radio is a hybrid C++ / Python system. The primitive signal processing blocks are implemented in C++. All graph construction, policy decisions and non-performance critical operations are performed in Python. All of the underlying runtime system is manipulatable from Python.
