In this study, the bit-rate and power-bandwidth (P-B) efficiency of wireless adaptive feedback communication systems (AFCS) are considered. The analysis is based on the results of AFCS optimization [1], [2]. It is shown that the capacity of optimal AFCS is equal to that of the forward channel in the initial n* cycles of the samples transmission, and decreases for n>;n*. Transmission in the "threshold" number of cycles n* provides "ideal" P-B trade-off and full utilization of the resources of the system.
