An Upper Bound for the Capacity of Amplitude-Constrained Scalar AWGN Channel
Borzoo Rassouli, Bruno Clerckx · IEEE Communications Letters · 2016
This letter slightly improves the upper bound in Thangaraj et al. for the capacity of the amplitude-constrained scalar Additive White Gaussian Noise (AWGN) channel. This improvement makes the upper bound within 0.002 bits of the capacity for (Eb/N0) ≤ 2.5 dB.
