Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The noncoherent capacity of stationary discrete-time fading channels is known to be very sensitive to the fine details of the channel model. More specifically, the measure of the set of harmonics where the por spectral density of the fading process is nonzero determines if capacity grows logarithmically in SNR or slor than logarithmically. An engineering-relevant problem is to characterize the SNR value at which this sensitivity starts to matter. ,  consider the general class of continuous-time Rayleigh-fading channels that satisfy the wide-sense stationary uncorrelated-scattering (WSSUS) assumption and are, in addition, underspread. For this class of channels,  show that the noncoherent capacity is close to the AWGN capacity for all SNR values of practical interest, independently of whether the scattering function is compactly supported or not. As a byproduct of our analysis,  obtain an information-theoretic pulse-design criterion for orthogonal frequency-division multiplexing systems.
