Improved method for digitizing bit synchronization

An improved method for digitizing bit synchronization for any random signal source comprises the following steps: delaying an inputted signal sequence at intervals, wherein the signal sequence contains at least more than one path of input signals; multiplying the input signals of each path respectively by at least more than one input signals of the local channels within one symbol period, the multiplied output values are accumulated and then averaged to get the average values within the symbol period; comparing the average values of each channel of each path of input signals, and outputting the selected average value of the path with the maximum average value and its corresponding decode; integrating the maximum average value of each path in a preset time window length, and comparing the integral values of each path, then selecting the path with the maximum integral value and outputting its corresponding decode. It can run well under the random signal resource and satisfy the requirement of real conditions, a
