On the Performance of Peaky Capacity-Achieving Signaling .. - Lun, Médard, Abou-Faycal (2003) (Correct)
....are characterized as those whose energy and fourth moment (kurtosis) in a fixed band scale inversely with the total bandwidth and the square of the total bandwidth respectively loosely speaking, those that spread energy more or less evenly over the entire available band. Subramanian and Hajek [3] instead considered a wide sense stationary uncorrelated scattering fading channel with a constraint on the fourth moment of the output signal and again found an inverse relation between capacity and bandwidth. Given an infinite band, capacity can instead be reached using peaky signaling, i.e. ....

.... term on the right hand side of (281) is nonnegative, 280) follows from (285) Particularizing Theorem 20 to the linear Ricean fading channel where (286) and is Gaussian with mean , independent of , we obtain the bound (287) which in the Rayleigh special case has been found recently in [38] [39]. Although (287) holds for all , it is not a tight bound. In fact, it is very coarse at all but small and it does not give the exact asymptotic second order behavior for vanishing . Under quite general conditions on the input and the channel (including non Gaussian channels) it is shown in [40] ....

....inversely with bandwidth in an appropriate manner (which induces a constraint on the fourth moment) the mutual information approaches zero with increasing bandwidth. This result has been shown with several variations in the channel model and the assumptions on the properties of the input signal [1, 2, 3]. Rather, given an infinite band, capacity can be reached using peaky signaling, i.e. transmitting with a low dutycycle frequency shift keying scheme. Such signaling is described as peaky because transmission energy is concentrated into narrow regions of time (owing to the low duty cycle) ....
