Chaotic time hopping based multiple access in BPSK-UWB system
Chaos based method of multiple-access in TH-UWB system is proposed. Power of multi-user interferences depends on probability density of chaotic map. Results are confirmed by computing numerically the BER for two chaotic maps. When pulse converges to Dirac system has the same performance as one use BPSK. For great number of users proposed method allow better BER than classical method.
