摘要

对于MIMO波束形成，本征波束形成(EB)技术提供了最好的性能，但代价是需要了解全信道信息。为了减少这种开销，提出了一种量化波束形成(QB)方法，即只使用一些反馈比特来计算合适的波束形成矢量。然而，QB在寻找波束形成矢量的复杂性方面存在缺点，并且对于大量的反馈比特来说更加困难。本文提出了一种名为角波束形成(AB)的新技术来克服QB的这一缺点。通过将多个数据流发送到4x4 MIMO系统来进行调查。研究了不同的数据流和反馈比特数对系统的影响。仿真结果表明，AB技术具有良好的性能，其性能与QB技术相当。

Angular beamforming technique for MIMO beamforming system

For MIMO beamforming, the Eigen Beamforming (EB) technique provides the best performance with the expense of knowing full channel information. To reduce such an expense, the Quantized Beamforming (QB) has been presented by using only some feedback bits to calculate the suitable beamforming vectors. However, QB has a drawback in the complexity of finding the beamforming vectors and it is more difficult for a lot of feedback bits. In this paper, the new technique named as Angular Beamforming (AB) has been presented to overcome such a drawback of QB. The investigations are undertaken by sending multiple data streams into 4x4 MIMO system. The effect of different data streams and number of feedback bits are studied. The simulation results indicate that AB technique performs very well and its performance is as good as QB.
