Decide frame and be meant that receiving terminal after receiving bit (bit) code stream of transmitting terminal input, by mating special character, promptly decides the frame byte, obtain a kind of method of frame head, achieve frame synchronous (frame synchronization).This method is extensive use of in present communication system.By deciding the frame byte, receiving terminal knows which bit constitutes a frame, with the accurate position of definite frame, thus the frame synchronization of finishing.
Different method for fixing frame has determined the time that achieve frame is synchronous, thereby has determined the service fulfillment or the time of business recovery.In the leggy modulating system, as DQPSK (Differential QuadratureReference Phase Shift Keying, difference four phase Quadrature Phase Shift Keying) system, may occur the problem of I/Q data flow bit negate during rectification at random, promptly the data behind the rectification may be the radix-minus-one complements of normal data.If radix-minus-one complement appears in the input traffic of receiving terminal, and receiving terminal uses predetermined framing byte that input traffic is carried out the framing processing, then can cause the business of frame synchronization to open.
Common solution is to decide the frame result by detecting at present, adjusts input traffic, until deciding the frame success:
At first, system detects to decide whether to contain among the frame result LOF (LOF, Loss of Frame) warning message, to judge present input data stream decided whether success of frame: if do not find the LOF warning message, it is successful to represent that then present input data stream decide frame; If find the LOF warning message, represent that then the problem of bit negate appears in the data behind certain (a bit) the road rectification in the input traffic, then the data behind the rectification of current a certain road are pressed the bit negate, trial carries out deciding frame to the input traffic after the negate; If the LOF warning message still occurs, then continue the data behind other No. one rectification are pressed the bit negate, again the input traffic after the negate is carried out deciding frame; Constantly so attempt,, enter frame synchronization (IF, InFrame) state until deciding the frame success.
