In code division multiple access (CDMA) communications systems multiple access interference limits the capacity of systems using conventional single user correlation or matched filter receivers. This paper considers multiuser detection from a combinatorial optimization viewpoint by implementing the genetic algorithm (GA) on the reverse link of an IS-95 CDMA system. Experimental results suggest that a GA multiuser detector provides an attractive alternative to other types of multiuser detectors with regard to the rate of convergence and improved bit error rates.
