摘要

在无线通信中，智能天线系统利用天线阵列获取传输信号的空间特征，并利用信号的空间特征或到达方向(DOA)的差异来正确获取所需的信号。这样可以减少同信道干扰，缓解多径传输引起的衰落现象，增加系统容量，提高通信质量。本文的目的是研究基于智能天线DOA的波束形成算法在宽带码分多址(W-CDMA)系统中的性能。仿真结果表明，与全向天线相比，采用智能天线的W-CDMA系统在特定信噪比下具有更低的误码率，在特定误码率下允许更多的用户接入系统，提高了系统容量。

Performance evaluation of DOA based beamforming in W-CDMA system

In wireless communications, a smart antenna system utilizes an antenna array to acquire the spatial signatures of the transmitted signals and uses the difference of the spatial signatures or the direction of arrival (DOA) of signals to correctly obtain the desired signal. This can reduce co-channel interference, mitigate the fading phenomenon caused by the multipath transmission, increase the system capacity and improve the communication quality. The purpose of this paper is to study the performance of the smart antenna DOA based beamforming algorithm applied to a wideband code division multiple access (W-CDMA) system. The simulation results show that a W-CDMA system with smart antenna, compared with that with an omnidirectional antenna, can have a lower bit error rate at the specific signal to noise ratio (SNR), allow more users to access the system at the specific bit error rate and increase the system capacity.
