1. Ranjbar, Mohammad. Optimal Signaling Strategies and Fundamental Limits of Next-Generation Energy-Efficient Wireless Networks.

Degree: PhD, Electrical Engineering, 2019, University of Akron

This dissertation provides an in-depth analysis of information theoretic aspects of next-generation energy-efficient wireless networks taking into consideration important impairments which are prevalent in such networks. The main focus is on the design of optimal signaling schemes and the calculation of the information theoretical limits of non-Gaussian channels and channels under non-linear quantization functions.In the first part we focus on the optimal signaling schemes and energy efficiency of point-to-point and multi-user communication channels under Gaussian-mixture aggregate interference. Because there does not exist any explicit expression of the mutual information for such channels, we face new challenges and the novelty in technical derivations and analysis makes our work stand out from the current state-of-the-art.The second part of this dissertation investigates the capacity region and detailed characterizations of capacity-achieving signaling schemes of a Multiple-Access Channel with two mobile users communicating to a base station equipped with 1-bit quantizers. Building upon these results, we demonstrate that any Π/2 circular symmetric input distribution having a constant amplitude is sum-capacity achieving. As a result, we establish the sum-capacity in closed-form. Advisors/Committee Members: Tran, Nghi (Advisor).

Subjects/Keywords: Electrical Engineering; Optimal Signaling, energy Efficiency, Wideband Slope, minimum bit energy, convex optimization, non-gaussian, gaussian-mixture, ADC, low-resolution ADC, capacity, capacity-achieving, sum-capacity, capacity region
