مجتمع متخصصین ایران - Direct sequence-code division multiple access (DSCDMA)
technique is used in cellular systems where users in
the cell are separated from each other with their unique
spreading codes. These systems suffer from multiple access
interference (MAI) due to other users transmitting in the cell,
channel inter symbol interference (ISI) due to multipath
nature of channels in presence of additive white Gaussian noise
(AWGN).
This paper presents an investigation on use of new type of
DSCDMA receiver called Genetic Algorithm based DS-CDMA
receiver. Genetic Algorithm is robust optimization technique
and does not fall into local minima, hence this gives better
weight optimization of any system.
Extensive simulation studies demonstrate the performance of
the different linear and nonlinear DS-CDMA receivers like
RAKE receiver, matched (MF) receiver, minimum mean
square error (MMSE) receiver using gold sequences and the
performance has been compared with GA based receiver. It is
seen that GA based DS-CDMA receiver performs much better
than other type of receivers.
