摘要
针对OFDM系统中信号的调制方式,提出一种基于高阶累积量的算法。该算法可以有效地抑制高斯噪声,实现OFDM信号调制方式的识别。文章给出了理论分析和计算机仿真。结果说明算法的性能稳定,复杂度低,具有较高的识别率。
A higher order cumulants algorithm is introduced, which can suppress the Gaussian white noise efficiently. Theoretical analysis and computer simulation is given. It is shown by the results that the algorithm is stable with a low complexity and it has a high correct rate to classify the modulation of OFDM signal.
