Performance evaluation of a multiple-cell CDMA radio system

Abstract

A statistical method for evaluating the performance measures of the base to mobile link of a multiple-cell CDMA system is presented. Specifically, techniques and expressions for estimating the short term average bit-error-rate (BER), service reliability and link availability are developed. The link performance is estimated for a mobile at the vertex of multiple adjacent cells. In the analysis, the system is assumed to employ coherent BPSK modulation and direct sequence spreading and the received signals are assumed to undergo Rayleigh fading, log-normal shadowing and frequency selective fading. The effects of power control and error correction are also investigated.<>
