Abstract :
The hardware and software interface to a programmable real-time RF propagation simulator is described. First, fading models are reviewed; and next, the digital filter design of the fade spectra filtering is detailed along with the implementation on a floating point digital signal processor (DSP). The hardware system design is given, followed by the application of this system to radio link propagation.
