摘要：

The present paper proposes a scheme of combining soft handoff (HO) and beam forming in physical layer and automatic repeat request (ARQ) in link layer for improving the performance of data service in cellular CDMA. A stop and wait ARQ scheme has been assumed for data service. Joint effects of beam forming and soft handoff reduce delay, BER and increase throughput significantly. Impact of several parameters of soft handoff and beam forming on data performance has been evaluated. Both the cases of perfect and imperfect beam forming have been investigated. Effects of DOA (Direction of arrival) estimation error have also been indicated on data service.
