摘要 DWCS(分布式无线通信系统)中的切换可分成两类:单天线切换和天线组切换。对选择固定虚拟小区大小方式的DWCS系统,天线组切换方式有较好的性能。为进一步提高切换的性能,一种位置和方向信息辅助的切换算法被提出,而且经过仿真研究其在不同定位精度下的性能,发现在20m以内精度下,该算法将能保持良好的稳定性,从而保证了其在DWCS中的可行性。 The handoff algorithms in DWCS were divided into two types： handoff between antennas and handoff between antenna sets. It was verified that the latter was more suitable for DWCS. Subsequently, a position location and direction assisted handoff algorithm was presented for achieving better handoff performance, and the simulation has shown that the improved algorithm is not sensitive to location errors within 20m. Thus it is feasible in DWCS.
