Abstract

The performance of trellis-coded quadrature phase shift keying (QPSK) in mobile radio communication channels characterized by fast Rayleigh fading is studied using Monte Carlo simulation. The receiver consists of one-bit and two-bit differential detectors followed by Viterbi decoding. This receiver improves the bit error rate of QPSK in additive white Gaussian noise channels. The simulation studies of this receiver to detect trellis-coded QPSK in fast Rayleigh fading are presented. The mobile radio channel simulator using a finite impulse response digital filter is described. Simulation results computed by Monte Carlo counting techniques are presented at different fading rates and signal-to-noise ratios
