技術說明

本發明揭示一種合作式通訊系統及方法，用於解決習知通訊系統之高峰均值功率比問題，該系統由一來源端耦接一中繼端及一目的端，該中繼端耦接該目的端，該來源端、該中繼端及該目的端之間的訊號傳送過程分為一第一時期及一第二時期，於該第一時期，該來源端傳送二原始訊號至該中繼端，該中繼端接收該二原始訊號混成之混合訊號後，旋轉該混合訊號之相位而產生一轉相訊號；於該第二時期，該來源端傳送該二原始訊號至該目的端，該中繼端傳送該轉相訊號至該目的端，該目的端依據該二原始訊號及該轉相訊號進行解碼。藉此，可確實解決上述問題。 This invention discloses a cooperative communication system and method which are used to solve the problem of high peak-average-power-ratio of the conventional communication system. The cooperative communication system is constructed by a source coupling to a relay and a destination, with the relay coupling to the destination. The signal transmission process between the source, the relay, and the destination is divided into a first interval and a second interval. Within the first interval, the source transmits two source signals to the relay. After a mixing signal mixed from the two source signals is received by the relay, the relay rotates a phase of the mixing signal to generate a phase-translated signal. Within the second interval, the source transmits the two source signals to the destination. Meanwhile, the relay transmits the phase-translated signal to the destination, and the destination executes a decoding process based on the two source signals and the phase-translated signal.
