Abstract

This paper describes a simulation approach to characterizing the performance of a coded PCM/FM modem operating on the classical Rician fading channel. In particular, the performance of short constraint length convolutional codes is considered in conjunction with Viterbi maximum likelihood decoding. The receiver consists of a narrow-band filter followed by an ideal limiter/discriminator. Primary interest is in the bit error probability performance as a function of E//b/N//0 parameterized by both the fading channel and receiver parameters. Particular attention is given to simulating the impulse noise appearing at the discriminator output. This is the ″click″ noise caused by encirclements of the origin by the instantaneous signal-plus-noise phasor. Results include the effects of channel memory and narrow-band receiver filtering effects on overall bit error probability.
