Appendix E. Gaussian Approximations for Spread Spectrum CDMA
This Appendix contains detailed mathematical analysis which provides expressions for determining the average bit error rate for users in a single channel, CDMA, mobile radio system. Using the expressions provided in this appendix, it is possible to analyze CDMA systems for a wide range of interference conditions. These expressions may be used to reduce or eliminate the need for time intensive simulations of CDMA systems in some instances.
In a spread spectrum, Code Division Multiple Access (CDMA) system using binary signaling, the radio signal received at a base station from the kth mobile user (assuming no fading or multipath) is given by [Pur77]
