Capacity of Channels with Amplitude Constraints

Brief Overview

Study of the capacity of additive channels with an amplitude constrain (i.e., peak power) on the input. Amplitude constrained channels commonly occur in practice, however, neither capacity nor optimal transmission schemes are unknown for such channels in general.
