摘　　要：Customers＇ satisfaction with services is reflected by quality of experience（QoE）.Insofar,most studies on cooperative communication have been focused on improving the QoE of source users.However,the improvement of a source user＇s QoE is obtained at cost of degradation of the relay user＇s QoE.On the other hand,cooperative communications can achieve performance similar to that of a conventional multiple-input multiple-output（MIMO） system by forming virtual MIMO arrays.Hence,to improve the QoE performance of relay users,this article proposes the concept of a belief threshold at the destination user and a new cooperative scheme based on the belief threshold destination（BTD） technique,while without decaying the BER performance of the communication system.Customers＇ satisfaction with services is reflected by quality of experience（QoE）.Insofar,most studies on cooperative communication have been focused on improving the QoE of source users.However,the improvement of a source user＇s QoE is obtained at cost of degradation of the relay user＇s QoE.On the other hand,cooperative communications can achieve performance similar to that of a conventional multiple-input multiple-output（MIMO） system by forming virtual MIMO arrays.Hence,to improve the QoE performance of relay users,this article proposes the concept of a belief threshold at the destination user and a new cooperative scheme based on the belief threshold destination（BTD） technique,while without decaying the BER performance of the communication system.
