QA-P-MMSE: A scalable and high-performance receiver for cell-free Massive MIMO with Quantized Fronthaul
This paper proposes a novel, scalable receiver scheme: the Quantization-Aware Partial MMSE (QA-P-MMSE) receiver, which significantly outperforms other scalable schemes, such as Maximum-Ratio (MR) and Partial-MMSE (P-MMSE), in terms of both average spectral efficiency and user fairness.
