A computer program to analyze spread-spectrum system performance
Abstract
A computer program was developed which analyzes and compares the performance of certain types of frequency hopping and psuedonoise (sometimes called direct sequence) spreadspectrum communication systems in the presence of hostile jamming. The program computes the probability of bit or word error as a function of the communication signal parameters (spectrum spreading methods, error-correcting coding, data modulation, bandwidth, etc) and the jamming parameters (jamming modulation, power, bandwidth). The output consists mainly of plots of error probability as a function of one or more of these parameters selected by the user. The plots are produced on an interactive computer graphics terminals, providing rapidly produced results and high user-computer interaction.
