Abstract-The mobile radio channel can be simulated as a
complex-valued random process with a time-varying variance.
This paper describes an implementation of that process using
a real-time Digital Signal Processing (DSP) technique. The simulator
design permits the user to select the simulation parameters,
including: vehicular speed, carrier frequency, ratio between
the line-of-sight component and the multipath component,
and the variance of average power. The design is based
on variable sampling rate DSP techniques, and offers a novel
solution to suppress the aliasing terms at intermediate stages
where access to analog filters is cumbersome and costly.
