摘要

针对多输入多输出(MIMO)信道，利用加权MMSE准则推导出一种联合优化的时空线性预编码器和解码器。我们表明，我们的解决方案提供了一个统一的框架，从这个框架中可以开发出一些知名的设计以及新的设计。作为一个例子，我们展示了如何设计一个基于QoS的预编码器和解码器，它们可以最佳地传输和接收独立的数据流，每个数据流具有不同的编码、调制和目标BER要求。

A generalized space-time linear precoder and decoder design using the weighted MMSE criterion

We derive a jointly optimum space-time linear precoder and decoder for a multi-input multi-output (MIMO) channel with delay-spread, using the weighted MMSE criterion. We show that our solution provides a unified framework, from which several well-known designs as well as new designs can be developed. As an example, we show how to design a QoS based precoder and decoder that can optimally transmit and receive independent data streams, each with a different coding, modulation and target BER requirements.
