Exact Capacity-Achieving Inputs of the Noncoherent Block-Rayleigh Channel at Every Coherence Length

In this paper, we study the capacity-achieving input of the single-antenna Rayleigh block-fading channel with coherence length T, an average power constraint and no channel state information at either end. Constant-norm signaling, in which every fading block carries the same ener...
