摘要: Adaptive transmitting antenna arrays hold great promise for increasing the capacity of mobile radio networks by reusing a channel among several users. To reuse bandwidth, array requires feedback information from receivers in order to track changes multipath environment. When is moving rapidly, required rates can become significant. We present new method transmission beamforming, which, exploiting subspace structure spatial channel, much lower data than previous methods.
