Abstract
Multicarrier spread spectrum (MC-SS) system employs frequency diversity, hence obtains the ability combating band-limited interference. In this paper, we consider a multicarrier direct sequence spread spectrum (MC-DS-SS) system, in which every sub-channel is spread by a pseudo number (PN) code respectively, making each sub-channel's bandwidth larger than jammer's. The system has the advantages of large processing gain, low interception probability, and robustness against partial band interference. We analyze bit-error ratio (BER) properties of MC-DS-SS system under partial band interference, and compare it with single carrier DS system. It is shown by the comparisons that whenever the diversity gain is observed, MC-DS-SS system always outperforms single carrier DS system under the same interference environment. When jammer spreads its bandwidth over the entire frequency range of desired signal, MC-DS-SS still outperforms single carrier DS-SS.
