Binary code phase offset calculation method and a binary code phase synchronization method by using the phase offset

摘要

The present invention is to provide a phase offset calculation method of binary code being used in a mobile communication system, a binary code error detection method for detecting errors occurred in the received binary code by using the phase offset of the binary code and a synchronization method of binary code greatly reducing an acquisition time by using the error detection. The present invention to calculate the phase offset of binary code includes a step of receiving the binary code Tⁱ(C) shifting with a period n, a step of calculating a binary code weight accumulation value by selecting the accumulator function weight value l of the binary code and then by applying the weight value to said binary code, a step of obtaining a phase shift value by shifting the phase of the binary code weight accumulator value, and a step of calculating the phase offset of the binary code by performing an operation of modulo n on said binary code weight accumulator value. Furthermore, an error detection method of binary code for detecting errors in a received binary code by using the phase offset calculation method of binary code and the synchronization method of binary code performing in high speed a synchronization acquisition of the phase synchronization signal by using the phase offset calculation method of binary code and the error detection method are provided.
