Abstract :
The system performance is analyzed using a new modulation scheme called time-hopping(TH) MN-ary biorthogonal pulse amplitude position modulation(MN BPAPM) for ultra wideband(UWB) systems with asynchronous multiple- access interference (MAI) in an additive white Gaussian noise (AWGN) channel. Closed-form expressions of symbol error rate (SER) and channel capacity are provided, then the simple expressions are obtained. The performance of TH MN BPAPM and MN-ary orthogonal PPM(MN OPPM) schemes are compared in terms of the SER in the end. It is shown that the TH MN BPAPM provides better performance with lower demodulator complexity that the TH MN OPPM system. Meanwhile, for the TH MN BPAPM system, the larger N leads to lower system SER and higher channel capacity.
