Abstract

The system performances of two different adaptive quadrature amplitude modulated code division multiple access multiuser detectors are evaluated. The adaptive multiuser detectors proposed are the minimum mean square error block decision feedback equalizer (MMSE-BDFE) and the successive interference cancellation (SIC) receiver. Our investigations show that for a COST 207 7-path Bad Urban Rayleigh fading channel, the MMSE-BDFE outperforms the SIC receiver in throughput performance terms for a target BER of 1%. However, this increased performance is achieved at the cost of a higher complexity
