Abstract

Cooperative communication can achieve diversity gain and increase the channel capacity. This paper proposes a novel cooperative scheme called Cooperative Step-Wise Demodulation, which utilizes low level demodulation to demodulate high level modulated signal cooperatively. This paper focuses cooperative scheme in multi-hop wireless networks. The bit error rate probability is analyzed. The comparison among the proposed scheme and the conventional scheme is made through simulation and soft-define radio based experiments. Results show that the proposed scheme has great potential in the performance improvement of cooperative communication.
