Abstract—Using cooperative transmission, two or more singleantenna users can share their antennas to achieve spatial diversity in a slow fading channel. One relaying protocol tha...
Abstract - We propose a new space-time code (STC) structure that can achieve generalized optimal diversity (GOD) with a reduced design complexity, and also provide an increased cod...
Abstract— The wireless medium contains domain-specific information that can be used to complement and enhance traditional security mechanisms. In this paper we propose ways to e...
