OFDM 系统中最大似然调制识别算法研究
Research on Maximum-Likelihood Modulation Identification Algorithms for OFDM Systems
摘要
Abstract
By the non-linear transformation to the observation sample,the modified sub-carrier and sub-band based modulation identification algorithms for OFDM system were presented.The effect of frequency off-sets on the performance of the maximum likelihood identification algorithm was eliminated by the transforma-tion.The simulation results showed that the algorithm had better performance as the normalize frequency off-sets was less than 0.1 5.关键词
