A low frequency hopping TCM-8 PSK adaptive RSSE receiver for TDMA wideband cellular mobile radio

A Monte Carlo simulation study of a combined FDMA/TDMA slow frequency-hopping trellis-coded 8 PSK adaptive reduced state sequence estimation (RSSE) receiver for high-capacity cellular mobile radio communications is presented. In order to assess the performance of this scheme, the dynamic behavior of the mobile radio channel has been simulated by means of a simple two-ray model, with a variable delay, tau , between the two rays. At the receiver, two Viterbi decoders are used, one of them (RSSE soft Viterbi decoder) to cope with the selective distortion introduced by the channel and the other (hard Viterbi decoder) to decode the binary trellis-encoded received sequence. Bit error rate (BER) is obtained as a function of signal-to-noise ratio (SNR) and with tau and Doppler spread as parameters.<
