Abstract

The paper presents a statistical and theoretical analysis of Nth-order diversity reception combined with equalization in a mobile radio channel. The diversity paths are statistically independent and each is characterized by the sum of multiple delayed and independent Rayleigh-fading beams. In modeling the multi-path radio performance, the authors take into account co-channel interference (CCI) generated by frequency reuse and additive white Gaussian noise (AWCN). The performance evaluations are made of average error probability and outage probability. The average error rate is determined by using a Monte Carlo simulation for a set of channel parameters such as signal-to-noise ratio (SNR), signal-to-CCI ratio (SIR) and equalization coefficients determined for this channel, etc. A quadrature amplitude modulation (QAM) is used in the signal analysis. Equalization-taps are determined by using minimum mean-squared error (MSE) criterion and it is expressed directly in terms of the channel parameters and modulation characteristics of the signal
