BlindOrthogonal Multiuser Detector

Multiuser detectors forthedetection ofCDMA signals trytomitigate theeffect ofmultiple access interference (MAI)and backgroundnoise, thelineardecorrelating multiuser detector isoneofthem.However, itcanreject the MAI optimally butenhances thenoise level. Thereisthesame probleminblindlinear decorrelating (BLD)detector. We in this paperpropose anewblind orthogonal multiuser (BOMU) detector, whichtrytomitigate boththeeffect oftheMAI and thenoisecomponent. We alsoprovide simulation results suggesting thatinmanycases theBOMU detector outperforms theBLD detector.
