Abstract
Recovery from transmission errors is facilitated by initializing state variables to prescribed values in both a digital encoder used in transmitting a signal and a corresponding digital decoder used in receiving the signal when the transmission channel becomes inactive. Additionally, the values of the encoder and decoder state variables are held constant for up to a prescribed interval upon the transmission channel becoming inactive. The state variables are held constant until either the prescribed holding interval elapses or the transmission channel becomes active. If the prescribed holding interval elapses before the transmission channel becomes active the state variables are initialized to the prescribed values. However, if the encoder or decoder transmission channel becomes active before the prescribed holding interval has elapsed, the encoder or decoder, respectively, returns to its normal operative state and the state variables are allowed to adapt.
