Abstract
This invention relates to a method and system for digitizing bit synchronization in wireless communication. The method comprises delaying at intervals an input signal sequence, which contains at least one path of input signals; multiplying each path of input signals respectively by input signals in at least one local channel within one symbol period, the results are accumulated and then averaged within the symbol period; comparing absolute values of the averaged values of each channel of each path of input signals, and choosing a maximum absolute value to output as a bit synchronization extremum of the path; comparing the bit synchronization extremums of each path of input signals, and choosing a path of input signals having a maximum extremum as a decoded data output. This invention utilizes DMR bit synchronization technology that facilitates digitalization and reduces calculation, thereby greatly increase data rate, save resources and reduce costs.
