Effect of fluctuated transmit power control in uplink link capacity of DS-CDMA packet mobile communication

摘要

In DS-CDMA packet mobile communications, slow transmit power control (TPC) was found to provide a link capacity larger than fast TPC. This is because, with slow TPC, the received signal power variations due to fading remain intact and this results in a larger capture effect. This paper proposes a new fast TPC that changes TPC target randomly in order to obtain the capture effect. It is confirmed by computer simulation that proposed TPC achieves larger link capacity than conventional slow TPC.
