Power-optimal MIMO two-way relay networks
… The problem we aim to solve is to minimize the total transmit power consumed in the entire network while certain quality-of-service constraints are satisfied at the transceivers. To do so, we optimize jointly the relays’ beamforming matrices and the transceivers’ transmit powers. We assume that …

Circuits and protocols for low duty cycle wireless systems
… which consumes a large fraction of the power in these devices, is the primary focus of this thesis. We present circuit (active RF, leakage management and timing) and protocol (medium access and coding) techniques for total power minimization in low duty cycle systems. First, we present a …

Multi-antenna relay network beamforming design for multiuser peer-to-peer communications.
… matrix to minimize the per-antenna relay power usage for given users’ Signal-to-Noise Ratio (SNR) targets. As the problem is NP-hard, we develop an approximate solution through the Lagrange dual domain. Through a sequence of transformations, we obtain a semi-closed form solution which can …
