本文考虑准静态瑞利衰落信道上的大规模 MIMO 无源随机接入问题。给定固定的消息长度和规定的信道使用数量，目标是构建一种编码方案，在固定的错误概率下最小化每比特能量。该方案与其他最先进方案的不同之处在于，它融合了活动检测、单用户编码、导频辅助和临时决策辅助迭代信道估计和解码、最小均方误差（MMSE）估计和连续干扰消除（SIC）。我们证明，当活跃用户数量超过 100 时，这些想法的适当组合可以大大优于最先进的编码方案，使其成为该机制中已知的最佳性能方案。
This article considers the massive MIMO unsourced random access problem on a quasi-static Rayleigh fading channel. Given a fixed message length and a prescribed number of channel uses, the objective is to construct a coding scheme that minimizes the energy-per-bit subject to a fixed probability of error. The proposed scheme differs from other state-of-the-art schemes in that it blends activity detection, single-user coding, pilot-aided and temporary decisions-aided iterative channel estimation and decoding, minimum-mean squared error (MMSE) estimation, and successive interference cancellation (SIC). We show that an appropriate combination of these ideas can substantially outperform state-of-the-art coding schemes when the number of active users is more than 100, making this the best performing scheme known for this regime.
