An Improved Transmission Scheme in Cooperative Communication System

Authors: Seung-Jun Yu, Hyoung-Kyu Song, Young-Min Ko

Abstract:

Recently developed cooperative diversity scheme enables a terminal to get transmit diversity through the support of other terminals. However, most of the introduced cooperative schemes have a common fault of decreased transmission rate because the destination should receive the decodable compositions of symbols from the source and the relay. In order to achieve high data rate, we propose a cooperative scheme that employs hierarchical modulation. This scheme is free from the rate loss and allows seamless cooperative communication.

Keywords: Cooperative Communication, high data rate, transmission scheme, hierarchical modulation
