Optimum detection of data modulated m-sequences using triple correlation receiver

Conventional intercept receiver based on second order signal (autocorrelation) processing are generally ineffective in detecting direct sequences spread spectrum if the spreading sequence are unavailable [1]. Previous work has shown that the triple correlation function provides a basis for such identification. This paper will study triple correlation receiver using different generating polynomial that generate code of length (127,255) to determine the factors that affect on chip error rate on the recovered data and describe which polynomial has the minimum chip error rate.
