在进行移动台辅助越区切换时
需要精确测量信道质量
并将它报告给基站.欧氏距离度量与解调信息序列相结合
可以用来测量信道质量.仿真结果表明平均的欧氏距离度量在使用不同的编码调制方案和不同的移动速度下
仍然可以提供可靠的信道质量度量;使用欧氏距离度量作为移动台辅助越区切换的判决依据
显著地减少了切换次数和切换时延
提高了系统性能.
It is important for mobile assisted handoff(MAHO)to accurately measure channel quality and report it to the serving base station.The Euclidean distance(ED)metric
associated with the decoded information sequence
is used as a channel quality measure
Simulations show that the averaged ED metric is a reliable channel quality measure which remains consistent across different coded modulation schemes and at different mobile speeds;ED metric works well for MAHO
reducing unnecessary handoffs and handoff delay.
