Method of increasing the efficiency of coding communications systems with information feedback

A method of increasing the efficiency of the coding communications systems with information feedback is suggested. The operational logic of such systems is described followed by general formulas used to determine the error probability, average energy consumption and average number of iterations. The essence of this method lies in the appropriate and controlled choice of thresholds in the feedback channel receiver. This method of processing the code combinations in the feedback channel allows escaping energy losses under small signal-to-noise ratios in the feedback channel and increasing the system's efficiency in the remaining cases. The technical realization of the suggested method is presented.
