Abstract :
A software program called SPREAD, developed for modeling and time/frequency domain simulation of spread spectrum systems, is discussed. It allows the representation of the very large bandwidth-time products that are characteristic of spread spectrum signals. Results of typical simulations of direct-sequence pseudonoise and frequency hopping (FH) signals are given. The program can be used to evaluate end-to-end bit error rate performance and to perform intermediate analysis of waveform characteristics that affect detectability. Results presented include the application of importance sampling to reduce the length of Monte Carlo simulations of FH systems, as well as preliminary results on the application of cyclic spectral analysis
