Abstract :
An on¿off sequence of an unknown signal pattern that is time-varying or fixed is dealt with. The optimum analogue feedback signal is obtained, which minimizes the average energy transmitted in the forward direction. The nonsupervised situation is also discussed. The effectiveness of the feedback method over the nonfeedback method is twice for the typical case.
