cdma2000 1X performance comparison with pilot power ratio
cdma2000 1X is the first commercialized mobile communication system that enables broadband data communication on the wireless mobile channel. cdma2000 1X provides a high data rate service on the forward link and the maximum total data transmission throughput is 384 kbps. The CDMA system uses the pilot channel for channel estimation and it is known that the coverage is determined by the pilot channel. High pilot power improves the system performance by good channel estimation. Nevertheless, high pilot power can decrease the system capacity because it consumes the forward link transmitted power. This paper reports simulation of the system capacity in the case of TIA/EIA-97-C recommended pilot power ratio and IS-95 operation criteria. From the simulation results, it is demonstrated that IS-95 operation criteria shows better performance than the TIA/EIA-97-C recommended specifications.
