A low-complexity GMSK demodulation timing synchronization method in burst communication

The invention discloses a GMSK demodulation timing synchronization method with low complexity in burst communication. In a short-time burst communication system, timing synchronization is generally completed by only one section of synchronization sequence, so that the reliability of subsequent data is reduced. The method comprises the following steps: 1, receiving and splitting a processed sequence, and carrying out matched filtering; 2, constructing a local synchronization sequence and a position index sequence, and calculating average power and related peak values; And 4, setting a thresholdvalue, and judging whether the processed sequence is effective or not; 5, intercepting partial sequences; and 6, calculating the phase, and rotating according to the phase. The method has the advantages of being simple in implementation framework, low in complexity and the like, and the demodulation performance of the method is superior to that of a traditional incoherent demodulation mode and close to that of coherent d
