Cooperative diversity method and cooperative diversity system using opportunistic relaying

Abstract

There are provided a cooperative diversity method and a cooperative diversity system using opportunistic relaying. In cooperative diversity wireless communications, an optimum relay is selected considering an interference effect between adjacent cells, and the selected relay transmits a data signal received from a transmitter to a receiver. Accordingly, an optimum relay is selected considering interference between channels not only in a single cell environment but also a multi cell environment, and a signal is transmitted to a receiver through the selected relay, thereby increasing transmission efficiency and improving reliability.
