摘要

研究了CDMA网络中存在波束形成和软切换的数据业务性能分析。研究发现，结合软切换的波束形成可以显著提高吞吐量，降低延迟和误码率。假设一个停止和等待ARQ方案。研究了完全波束形成和不完全波束形成两种情况。还指出了到达方向估计对数据业务的影响。

Performance of Data Services in Cellular CDMA in Presence of Soft handoff and Beamforming

Performance analysis of data services is studied in CDMA network in presence of beamforming and soft handoff (HO). Beamforming in conjunction with soft handoff is found to enhance throughput and reduce delay and BER significantly. A stop and wait ARQ scheme has been assumed. Both the cases of perfect and imperfect Beamforming are investigated. Effects of DoA (direction of arrival) estimation have also been indicated on data service.
