A NOVEL SEQUENCE DETECTION WITH CHANNEL CORRELATION INFORMATION AND ITS PRACTICAL IMPLEMENTATION IN FAST FADING CHANNEL

摘要

In this paper, a novel sequence detection method based on codebook with channel correlation information (CCI) for the reliable feedback of CQI (Channel Quality Information) in the uplink fast feedback channel is proposed, which utilizes the codebook based maximum likelihood detection method. Using the relatively less training frames, we can get an accurate approximation of the statistical CCI for practical implementation. Thus, we will show that with this kind of information the system performance, such as PER, is much better than the conventional correlation detection method.
