论文摘要
本文表征了大量多源空间调制MIMO系统的性能，当使用最小二乘法的正则化形式用于检测。对于通用失真函数和右单位不变的通道矩阵，得出了该类别检测器所实现的每平方传输速率和渐近失真。为了调用渐近表征，我们解决了两个特定的应用。也就是说，我们得出了通过计算上可缩减的最佳贝叶斯检测器达到的错误率，并提出了一种有效的方法来调整套索型检测器。我们通过各种数值实验进一步验证我们的推导。
This paper characterizes the performance of massive multiuser spatial modulation MIMO systems, when a regularized form of the least-squares method is used for detection. For a generic distortion function and right unitarily invariant channel matrices, the per-antenna transmit rate and the asymptotic distortion achieved by this class of detectors is derived. Invoking an asymptotic characterization, we address two particular applications. Namely, we derive the error rate achieved by the computationally-intractable optimal Bayesian detector, and we propose an efficient approach to tune a LASSO-type detector. We further validate our derivations through various numerical experiments.
