RF Channel Simulation

Though GNU Radio was first thought of for being a software defined radio (SDR) platform capable of receiving or transmitting arbitrary waveforms such as to take the airwaves back to the people, the development of the software has lent itself very useful for the possiblity of abstracting statistical RF channel models for simulations.

For what purpose would this be a good idea? Who needs simulation, you ask?

When designing adaptive equalizers or RAKE receivers, it might be good to know the typical performance given a specific channel type. For some cases - such as dense areas like urban settings it might be better to use one setting versus another.

I think that RF channel simulation blocks, though boring and possibly not quite as exciting as some of the other blocks, will bring GNU Radio to the forefront of SDR development and might possibly lead to the software package being used more commercially.
