摘要
首先对无线传播模型进行了归纳;然后对TD-SCD-MA的上/下行链路预算和基站覆盖半径进行了计算,并分析了覆盖受限方向;最后讨论了3G混合业务下的基站覆盖半径以及与WCDMA覆盖方面的差异。
It first describes link budget parameters choosing analysis, and then summarizes radio propagation models. Meanwhile, it calculates TD-SCDMA uplink ＆ downlink budget and coverage radius of base station, analyzes coverage limitation direction. Finally it discusses coverage radius of base station in mixed 3G operation mode and differences between TD-SCDMA and WCDMA coverage.
