Fuzzy recursive symbol-by-symbol detector for single user CDMA receivers
Joan Bas, A. na Perez Neira, Miguel Angel Lagunas · 2002
The Bayesian or maximum a posteriori (MAP) symbol-by-symbol detector allows minimum BER single user detection in CDMA systems with less memory requirements than the multiuser maximum likelihood sequence estimator. This work proposes a further complexity reduction by developing a fuzzy recursive implementation of the Bayesian detector. Simulation studies demonstrate the almost optimal performance of the developed fuzzy detector. The resulting system offers a performance v.s. complexity trade-off very appealing for detection in a 3/sup rd/ generation mobile handset.
