Pseudo-chaotic time hopping (PCTH) is a recently proposed encoding/modulation scheme for UWB (ultra-wide band) impulse radio. PCTH exploits concepts from symbolic dynamics to generate aperiodic spreading sequences, resulting in a noiselike spectrum. In this chapter we present the signal characteristics of single-user PCTH as well as a suitable multiple access technique. In particular, we provide analytical expressions for the BER (bit-error-rate) performance as a function of the number of users and validate it by simulation.
