An Upper Bound for the Capacity of Amplitude-Constrained Scalar AWGN Channel (1605.01211v1)
Published 4 May 2016 in cs.IT and math.IT
Abstract: This paper slightly improves the upper bound in Thangaraj et al. for the capacity of the amplitude-constrained scalar AWGN channel. This improvement makes the upper bound within 0.002 bits of the capacity for $\frac{E_b}{N_0}\leq 2.5$ dB.
