IMPACT OF A NONFADING GAUSSIAN CHARACTERIZATION OF INTERFERENCE ON PORTABLE RADIO LINK ANALYSIS

In order to make the analytical evaluation of portable radio link perf ormance tractable while avoiding lengthy simulations, intersymbol inte rference and cochannel interference are often modelled as non-fading, gaussian noise. This paper investigates the viability of such an appro ach for wide-band channels where equalization and space diversity are used to combat interference and signal fading. Comparisons or results obtained using such an assumption of interference with those of a simu lation-based approach indicate that as long as the number of cochannel interferers is smaller than the space diversity order, the variance o f the gaussian interfering symbols can be adjusted to provide a reason able estimate of performance over error rates of interest.
