标题： Low-Complexity Detection of Permutational Index Modulation for Noncoherent Communications

摘要： 这项工作提出了一个用于无线通信的大量SIMO方案，采用单次非相干检测。 它基于OFDM上的排列索引调制。 其核心原理是通过将固定值集合映射到OFDM子载波的方式顺序来传递信息。 获得了一种球面码，该码对信道失真具有更好的鲁棒性。 提出了一种基于数据二次度量排序的简单检测器。 通过利用统计信道状态信息和硬化技术，实现了接近ML的误差性能，并且具有低复杂度的实现。 显示英文摘要

摘要： This work presents a massive SIMO scheme for wireless communications with one-shot noncoherent detection. It is based on permutational index modulation over OFDM. Its core principle is to convey information on the ordering in which a fixed collection of values is mapped onto a set of OFDM subcarriers. A spherical code is obtained which provides improved robustness against channel impairments. A simple detector based on the sorting of quadratic metrics of data is proposed. By exploiting statistical channel state information and hardening, it reaches near-ML error performance with a low-complexity implementation.
