Abstract

In this paper, we investigate the performance of the orthogonal complementary code (OCC) based direct sequence ultra wideband (DS-UWB) system. OCC has perfect partial autocorrelation and cross-correlation characteristics. With the application of OCC in DS-UWB system, we can offer multiple access interference (MAI) free operation in both synchronous and asynchronous transmissions over MAI-AWGN channel. Theoretical analysis illustrates that multipath interference (MI) as well as MAI can be also mitigated over lognormal multipath fading channels in OCC based DS-UWB system. Our simulation also shows the superiority of the OCC based DS-UWB to unitary code based system.
