ISI and Self-Noise Reduction Using Symbol-Rate Adaptive Receiver within a Detection Guided Rake Receiver

Code division multiple access (CDMA) systems use the spread spectrum technology to accommodate more number of users without interference and the RAKE receiver concepts to minimize ISI resulting from multipath effects. The ideal approach is to match the number of multipath signals with the number of...

Zusammenfassung:Code division multiple access (CDMA) systems use the spread spectrum technology to accommodate more number of users without interference and the RAKE receiver concepts to minimize ISI resulting from multipath effects. The ideal approach is to match the number of multipath signals with the number of correlators, but this would be a waste of resources. This paper incorporates a new signal detection technique which is used to decide the number of correlators required for demodulating the `important' multipath signals. System performance improvement is quantified and compared with the conventional technique in terms of SNR.
