Multiple-in-multiple-out network-coded amplify-and-forward relaying scheme for three node bidirectional cooperation

Abstract

A method and apparatus are described including receiving a first signal including first data in a first time slot of a first channel (), receiving a second signal including second data in a second time slot of a second channel (), determining a first pre-coding matrix (), determining a second pre-coding matrix (), applying the first pre-coding matrix to the first data to produce pre-coded first data (), applying the second pre-coding matrix to the second data to produce pre-coded second data (), generating a third signal by combining the pre-coded first data and the pre-coded second data () and transmitting the third signal on the first channel and on the second channel (). Also described are a method and apparatus including transmitting a first signal (), receiving a second signal including a first training sequence () and decoding the second signal by removing the first training sequence and removing the first signal ().
