摘要

下一代移动服务，如可变带宽;通过使用新技术和新系统，使具有移动性和个性化服务的桌面/多媒体成为可能。为了以无线方式提供这些业务，传统的波束形成无法满足对数据速率、链路质量、频谱效率和移动性的要求。因此，新的波束形成技术对于提高无线通信系统的频谱效率至关重要。本文研究了一种基于分数阶傅立叶变换(FrFT)的微蜂窝环境下AWGN信道的最优波束形成方法，在不增加额外计算成本的情况下降低MSE。结果是通过在微蜂窝环境中使用基于FrFT的移动和加速源波束形成实现的。

Fractional Fourier transform based beamforming in micro-cellular environment of wireless communication systems

The next generation mobile services like variable bandwidth; desktop/multimedia with mobility and service personalization shall be enabled by putting new technologies and systems in use. In order to provide these services in wireless fashion the requirements on data rate, link quality, spectral efficiency, and mobility cannot be met with conventional beamforming. Therefore new beamforming techniques are essential to increase the spectral efficiency of wireless communication systems. In this paper a fractional Fourier transform (FrFT) based optimal beamforming in micro-cellular environments over AWGN channel is considered for reducing MSE at no extra computational cost. The results are achieved by use of FrFT based beamforming for a moving and accelerating source in a micro-cellular environment.
