智能天线中的自适应算法又称为数字波束成形算法,其中,盲自适应算法是不需要专门的训练信号或确定信号,节省了因接收训练序列和导频信号而占用的频谱资源,提高了频谱利用率。因此,盲自适应波束形成算法受到越来越多的关注。本文主要对现有的各种盲算法原理进行逐一介绍,然后对比了各种算法的优点。
智能天線中的自適應算法又稱為數字波束成形算法,其中,盲自適應算法是不需要專門的訓練信號或確定信號,節省瞭因接收訓練序列和導頻信號而佔用的頻譜資源,提高瞭頻譜利用率。因此,盲自適應波束形成算法受到越來越多的關註。本文主要對現有的各種盲算法原理進行逐一介紹,然後對比瞭各種算法的優點。

Adaptive algorithm for smart antenna is also known as digital beamforming algorithms.In respect that the blind adaptive algorithm which does not require the specialized training or determine signals,can improve the spectral efficiency since it can save the receive spectrum resources occupied by training sequences and pilot signals.There is growing concern about the blind adaptive beamforming algorithm.In this paper,I first give a sketch of the existing blind algorithms,and then compare their advantages.
