摘要

摘要: 该文针对全盲条件下单接收天线的空时分组码(STBC)识别问题，提出一种基于四阶累积量识别方法。使用接收信号的四阶累积量作为特征参数，利用高阶累积量对零均值高斯噪声不敏感的特性，首先求取各种STBC的四阶累积量理论值，再对采样信号四阶累积量进行区间检测，从而实现STBC的识别。该算法不需要信道信息和噪声参数，仿真结果表明，该算法在单天线条件下性能较好。

Abstract: A novel and efficient algorithm is proposed for Space-Time Block Code (STBC) classification, when a single antenna is employed at the receiver. The algorithm exploits the discriminating features provided by the forth-order cumulants of the received signals. Higher-order cumulants (of order greater than 2) are used to eliminate the impact of noise. Firstly, the theoretical value of the different STBCs is caculated, then the samples of STBCs are classified with an interval detector. It does not require estimation of the channel information and signal-to-noise ratio of the transmitted signal. Simulation results show that the proposed method for blind recognition of STBC achieves good performance.
