Frequency-occupation and throughput analysis of hybrid spread spectrum (DS/FH) network

Abstract

This paper introduced a system employing hybrid DS/FH spread spectrum (SS) coupled with RS forward error-control coding. By the flexible redefinition of frequency-occupation and frequency-collision event, the frequency-occupation probability of the DS/FH SS network was analyzed. This probability was based on the simultaneous transmission number threshold and discussed in both synchronous and asynchronous circumstances, respectively. The network throughput based on the packet correct reception probability was analyzed. Two models which had finite and infinite population respectively was discussed. Finally, simulation results were given.
