Abstract

Performance prediction for wideband communications systems requires a realistic simulation of the RF channel time and frequency-varying characteristics. It is well known that a lapped-delay line filter with time-varying coefficients can be used to represent a frequency selective channel. However, generating the coefficients required to model various scintillation and multipath conditions is not a simple task. The paper describes a software frequency selective channel simulator and the channel effects modeled using a complex exponential series approximation to the channel scattering function. Examples of using the software simulator to create and validate channel models are discussed.
