From Compact MIMO to Massive MIMO
, 2022 We study information theoretic design of compact antenna arrays and nonlinear precoding for multiuser MIMO channels with coarsely quantized alphabets. For the RF front-end design, it is shown that a class of lossless multiport matching networks maximizes information rates at any antenna spacing.
