研究了多输入多输出（MIMO）信道量化器和线性接收机的联合优化问题。我们的方法是基于均方误差（MSE）的标准，考虑到量化的影响。我们推导的一个重要方面是，我们不做不相关的白色量化误差的假设。对改进滤波器的性能以及量化的影响进行了理论和实验研究。此外，我们提供了一个下界的能力，这个通道。通过仿真，我们证明了我们的方法的实用性。
We investigate the joint optimization of quantizer and linear receiver for the quantized multi-input multi-output (MIMO) channel. Our approach is based on a mean square error (MSE) criterion, taking into account the effects of quantization. An essential aspect of our derivation is that we do not make the assumption of uncorrelated white quantization errors. The performance of the modified filter as well as the effects of quantization are studied theoretically and experimentally. Furthermore, we provide a lower bound on the capacity of this channel. Through simulation, we demonstrate the usefulness of our approach.
