摘要

我们提出了一种GSM下行波束控制技术，即在基站使用多天线进行传输。目标是降低下行链路干扰水平，从而增强容量和质量。仿真结果表明，在上行链路平均C/I大于-8 dB且采用跳频的情况下，该技术产生的干扰(定义为在期望的移动设备上给定一定功率的发射功率总量)比理论最小值多0.9 dB。

A downlink beam steering technique for GSM/DCS1800/PCS1900

We propose a technique for downlink beam steering in GSM, i.e transmission with multiple antennas at the base station. The objective is to reduce the downlink interference level and thereby enable capacity and quality enhancements. The simulation results indicates that the proposed technique generates less than 0.9 dB more interference (defined as the total amount of transmitted power given a certain power at the desired mobile), than the theoretical minimum, provided that the mean uplink C/I is better than -8 dB, and frequency hopping is applied.
