A Numerical Comparison Between FHSS and DSSS in Satellite Communication Systems with On-Board Processing

The FHSS and DSSS signals are widely used in military satellite communication systems. In this paper a new concept of "normalized throughput of information" is proposed according to the property of jammed signals, the performance of FHSS and DSSS signal with on-board processing is compared based on the new concept. We conclude that performance of FHSS signal is better than that of DSSS signal, and FHSS signal is suitable to be used in military satellite communications.
