摘要

中文摘要: 为了保证主用户的通信质量和提高次用户的频谱利用率，提出了次用户间协作检测以及主用户和次用户协作通信的多信道认知无线电模型。模型中，次用户协作检测到主用户存在时，能够在所有子信道中使用半个帧协作主用户通信和剩下半个帧传输自身数据；通过联合分配次用户和功率，在保证主用户通信质量的同时，最大化次用户吞吐量。仿真表明：相比传统的非协作模型，提出的协作模型能够使主用户和次用户的吞吐量都有所提高。

Abstract

Abstract:A multi-channel cognitive radio model was proposed to guarantee the communication quality of primary user (PU) and improve the spectrum utilization of secondary user (SU). This model was implemented through cooperative detection between SUs and cooperative communication between SU and PU. When PU’s presence was detected by SU’s cooperative detection

PU’s data was relayed through SU’s cooperative communication in half a frame

and then SU’s data was transmitted by itself in the left frame. While PU’s communication quality was guaranteed

SU’s throughput was maximized through jointly allocating SU and power. Simulation results showed that compared with the traditional non-cooperative model

both the throughputs of PU and SU are improved in the proposed cooperative model.
