Capacity, throughput, and delay analysis of a cellular DS CDMAsystem with imperfect power control and imperfect sectorization

摘要

An analytical model is developed to evaluate the performance of ancellular slotted DS CDMA system in terms of user capacity, throughput,nand delay for the reverse link, i.e., from mobile to base station,nconsidering interference from both home cell and adjacent cells. Thenuser capacity is studied for voice communications and the throughput andndelay are investigated for data communications. The effect of bothnimperfect power control and imperfect sectorization on the performancenis investigated. It is shown that the system is rather sensitive tonsmall power control errors and that voice activity monitoring andnsectorization are good methods to improve the performance of cellular DSnCDMA systems
