Two microphone based direction of arrival estimation for multiple speech sources using spectral properties of speech
A two microphone direction of arrival (DOA) estimation technique for multiple speech sources is developed which exploits speech specific properties, namely sparsity in time-frequ...

High Rate Two-Way Amplify-and-Forward Half-Duplex Relaying with OSTBC
—In this paper, we derive tight upper and lower bounds for the average sum rate of two-way amplify-andforward (AF) half-duplex relaying, which show that two-way AF half-duplex re...

A Surface Phase Field Model for Two-Phase Biological Membranes
We study vesicles formed by lipid bilayers that are governed by an elastic bending energy and on which the lipids laterally separate forming two different phases. The energy laden...

Memoryless Relay Strategies for Two-Way Relay Channels: Performance Analysis and Optimization
— We consider relaying strategies for two-way relay channels, where two terminals transmits simultaneously to each other with the help of relays. A memoryless system is considere...
