Abstract :
Pseudo-chaotic time hopping (PCTH) is a recently proposed modulation scheme for UWB impulse radio. PCTH exploits concepts from symbolic dynamics to generate aperiodic spreading sequences. In this paper, we present a general analytical expression for the average bit error rate (BER) performance of a synchronous multi-access PCTH system as a function of the cross-correlation between the users´ signatures in an additive white Gaussian noise (AWGN) channel. Also, it is shown that with enough users an error floor in the BER can develop.
