基于高阶累积量的LCP-GLSTBC-OFDM信号调制识别
Modulation Recognition Based on HOC for LCP-GLSTBC-OFDM Signals
摘要
Abstract
Based on high - order cumulates, a novel recognition algorithm is proposed for LCP - GLSTBC ( Group Layered Space - Time Block Coding) OFDM ( Orthogonal Frequency - Division Multiple) signals to distinguish multi - carrier modulated signals (OFDM) from single - carrier modulated signals ( MPSK and MQAM). The proposed algorithm can be used to directly process inter - frequency signals without the prior information about the transmit signal and the channel noise. Simulation results confirm the validity of the proposed algorithm and show that over 90% correct classification rate could be reached when SNR is above 5 dB.关键词
