Abstract

The paper presents the statistical and theoretical analysis of channel capacity with quadrature amplitude modulation (QAM) and Nth-order diversity reception in cellular and PCS 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, the authors take into account co-channel interference (CCI) generated by frequency reuse and additive white Gaussian noise (AWGN). The Shannon capacity of channel model and actual data rate can be supported by the optimum receiver structure with equalizer are derived as a function of system parameters such as signal-to-noise ratio (SNR) and signal-to-CCI ratio (SIR), etc. The numerical results for Shannon capacity and actual channel capacity in terms of outage rate with a given error probability threshold are obtained by Monte-Carlo simulation
