Abstract: Probabilistic shaping is widely employed in local oscillator-based coherent optical systems to improve receiver sensitivity and provide rate adaptation. This widespread adoption has been enabled, in part, by simple closed-form solutions for the optimal input… read more here.

Abstract: Upper and lower bounds on the minimum mean square error for additive noise channels are derived when the input distribution is constrained to be close to a Gaussian reference distribution in terms of the Kullback–Leibler… read more here.
