摘要

cdma2000 1X是第一个在无线移动信道上实现宽带数据通信的商用移动通信系统。cdma2000 1X在前向链路上提供高数据速率业务，最大总数据传输吞吐量为384kbps。CDMA系统使用导频信道进行信道估计，并且已知覆盖范围由导频信道决定。高导频功率通过良好的信道估计提高了系统性能。然而，高导频功率会消耗前向链路传输功率，从而降低系统容量。本文模拟了TIA/EIA-97-C推荐导频功率比和IS-95操作准则下的系统容量。仿真结果表明，is -95操作准则的性能优于TIA/EIA-97-C推荐规范。

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.
