Bit error correlation in Rayleighfading channels
Abstract
A model for binary data transmission is presented based on the wellknown Rayleigh model for the signal envelope of frequencynonselective mobile radio channels. This uses a binary symmetric channel with timevarying transition probabilities, which are controlled by the signal envelope. It is shown that only the bit error rate of the transmission scheme in additive white Gaussian noise and the Doppler power spectrum are required to determine the error sequence. The model makes it possible to investigate the bit error characteristics by means of software simulations as well as by theoretical calculations. This paper focuses on the influence of the Doppler spectrum on the bit error correlation (i.e., the probability that the kth bit following an error is also an error). In particular, an expression is derived, which relates these quantities directly. Typical Doppler spectra and their corresponding bit error correlations are discussed. Furthermore, the theoretical results are verified by software simulations.
