We study the realisation of a deterministic channel modeling which allows the construction of a realistic received waveform from a wireless spread spectrum multiple-access (SSMA) using time hopping (TH) modulation. The goal is to reach the symbol decision from a simulated waveform. This paper explains how to use the uniform theory of diffraction (UTD) method combined with a ray tracing to obtain the received TH modulation waveform in indoor or outdoor environment.
