Deterministic Formulization of SNR for Wireless Multiuser DS-CDMA Networks

Wireless multiuser receivers suffer from their relatively higher computational complexity that prevents widespread use of this technique. In addition, one of the main characteristics of multi-channel communications that can severely degrade the performance is the inconsistent and low values of SNR that result in high BER and poor channel capacity. It has been shown that the computational complexity of a multiuser receiver can be reduced by using the Transformation Matrix (TM) algorithm. In this paper, the authors provide quantification of SNR based on the computational complexity of TM algorithm. They show that the reduction of complexity results high and consistent values of SNR that can consequently be used to achieve a desirable BER performance.
