Abstract:

A multiple access method based on complete complementary codes in UWB (ultra wideband) communication was presented. The zero crosscorrelation of complete complementary codes ensured it as the signature code about user. The decoding of the receiver employed the algorithm about shift and add to decode the intended user's information. The principle of the proposed receiver and the reason why the receiver could suppress multiple access interference (MAI) were illustrated. The performance analysis and simulation results show that the proposed multiple access method based on complete complementary codes can accommodate better performance on suppressing MAI than THPPM UWB system.
