According to length divided by interleave depth, the depth of the data interlacing is an integer value more than 1.
The time counting label tkMaximum value be one be more than 1 integer value, often send a frame data, time counting
Label tkThen it is incremented by 1, as time counting label tkAfter the maximum value for reaching setting, next time counting label tkAgain it is opened from 1
Begin to count.
If time counting label tkIt is inserted into former transmission data, then existsIt is middle by time counting label tkIt goes
It removes；If time counting label tkIt is to replace former transmission data, then existsIt is middle to remove time counting label, then by the time
Count label tkThe clear data lacked on position is obtained by the way of front and back point data interpolation or filtering.Pass through receiving terminal
Time counting labelSerial number judge whether there is frame losing, can while in receiving terminal by the time counting label numerical value lacked
To obtain the serial number of frame losing, by by lost data after receiving terminal rearrangement before and after adjacent data into row interpolation or
Filtering obtains lost data value.
Further, receiving terminal counts label by -1 frame time of kth received beforeTo determine whether occurring
Frame losing；If meetingWhen, then frame losing phenomenon does not occur, ifWhen, then frame losing phenomenon occurs.
Further, when the frame number continuously lost is more than 1, i.e.,When；Receiving terminal can be by being more than
The data of frame obtain the lost data value more than 1 frame into row interpolation or filtering before and after the loss data of 1 frame.
The beneficial effects of the invention are as follows：
Compared to using automatic repeat request agreement, the present invention to be the transmission method of complete forward direction, receiving terminal weight is not needed
