The Detection and Recognition of m-Sequence Using Higher-Order Statistical Processing
基于高阶统计处理技术的m-序列检测及识别

m-sequence is one of the most widely used codes in spread spectrum communications. The triple correlation function(TCF) of m-sequence, the partial triple correlation function of m-sequence and its peak feature are studied and described in this paper. Then a detection method and a recognition standard of m-sequence are proposed based on the peak feature of the partial TCF. It is testified by simulation that the peak feature of the partial TCF is same as that of the TCF during the corresponding intercepted section. With the peak feature m-sequence can be detected and recognized and this is the basis for detecting and recognizing the direct sequence spread spectrum signals. The detection method and the recognition standard of m-sequence have been proved available by the simulation.
