论文摘要
本文考虑了准静态雷利褪色渠道上的巨大MIMO未包含的随机访问问题。给定固定的消息长度和规定的通道使用数量，目的是构建一个编码方案，该方案可将每位能量的能量最小化，但要以固定的误差概率约束。所提出的方案与其他最先进的方案不同，因为它融合了活动检测，单用户编码，试点辅助和临时决定迭代的迭代通道估计和解码，最小值平方误差（MMSE）估计以及连续的干扰取消（SIC）。我们表明，当活动用户的数量超过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，这使得这是该制度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.
