This invention discloses a data balance method in meteoric trace communication. The theory is that the initial evaluation vector of the channel parameter even processes the received baseband distortion signals to output decisive data to recover the original sent signals. The method includes the following steps: The channel parameter evaluation vector is got according to its initial evaluation vector and the received signals to compute out the al states path branch metric gain of the received signals further to get the branch meter of each state path and finds out the metric state with the minimum branch meter, then to delete the threshold and state then to backtrace the path and output related decisive signal.
