Fuzzy based chip level based receiver for direct sequence-code division multiple access communication system
Santosh Kumar Panda, Sarat Kumar Patra · 2005
This paper investigates the problem of chip level based (CLB) receivers for direct sequence code division multiple access (DS-CDMA) communication system. A radial basis function (RBF) receiver provides the optimum receiver performance for this system. We propose a fuzzy implementation of the RBF receiver. This fuzzy receiver provides considerable computational complexity reduction with respect to RBF receivers. Additionally this fuzzy receivers has the capability to provide exactly the same performance in terms of bit error rate (BER) as the optimum RBF receiver. Extensive simulation studies validate our finding.
