A synchronous blind equalization algorithm

This paper discusses the synchronous blind equalization algorithm which combines the synchronization technology and the Blind equalization algorithm. We analysis the importance of the synchronization technology in the underwater acoustic (UWA) communication by these algorithms. The data receives interference when it passes a multipath channel in the UWA communication. The disturbed signal will cause error code at the receiving end. But if we use these synchronous blind equalization algorithms, the receiving end can receive the correct message, because the blind equalization algorithm can compensate the disturbed data and the synchronization technology can find the head of the send message. This paper will make the synchronization technology combines with the basic Constant Modulus Algorithm (CMA) and the T/4 space equalizer of CMA algorithm (T/4-CMA). Then we will discuss the feasibility of these algorithms by the theory and the characteristic of the blind equalization with or without the synchronization technology by the simulation. The foundation works have been established for the farther research.
