Abstract

We propose a method to approximate the bit-error-rate (BER) performance of CDMA systems employing sample-matrix-inversion (SMI) maximum-signal-to-interference-plus-noise-ratio (MSINR) and SMI minimum-variance-distortionless-response (MVDR) linear receivers. In the proposed method, two forms of the Gaussian Q-function are approximated by finite series of exponentials and exponentially decaying cosines that are optimized using a relative error measure. The proposed method provides highly accurate closed form approximations to the BER performance for a wide range of practical scenarios with very low complexity
