摘要：

The orthogonality factor was, used to simplify the expression of the E-b/N-0 of a mobile station communicating with a single base station in the forward link of CDMA systems. This paper extends the orthogonality factor to express the E-b/N-0 of a mobile station communicating with multiple base stations by using the channel-gain matched combination approach. A simplified expression of the E-b/N-0 is derived by averaging over fast fading and using average orthogonality factor. This new expression of E-b/N-0 simplifies the capacity and outage calculations of the CDMA systems in the forward link. The relationship between the average E-b/N-0 in practical CDMA systems and that obtained using the simplified model is discussed. The analysis. shows that averaging over fast fading leads to a conservative evaluation of the CDMA system performance.
