The system provides correction for error signals caused by noise in the transmission channel in digital signals or analog signals which have been digitized. The first or second differential of the quantized values is taken and encoded. One or more reliable update signals per data block are included in the transmitted signal. Using any difference between an update signal value and the corresponding actual received signal value, an error signal in time reverse sequence is reconstructed in the receiver. This signal is reversed and subtracted from a signal containing the error signal to produce an accurate output signal.
