中文摘要：
为了提高宽带认知无线电（Cognitive Radio，CR）和主用户（Primary User，PU）的传输速率，提出了CR和PU之间协作通信的方案以及CR的最优子信道功率分配方法．当检测到PU存在时，该方案允许CR使用半个帧传输数据，使用剩下的半个帧帮助PU协作传输．基于此方案提出的功率分配能够使CR在不影响PU的同时获得更大的传输速率．仿真表明：相比传统的非协作通信，提出的方案能够使CR和PU的传输速率同时获得提高．
英文摘要：
In order to improve the transmission rates of cognitive radio （CR） and primary user （ PU ）, the cooperative communication scheme between CR and PU and the optimal sub-band power allocation are proposed respectively. If the presence of the PU is detected, the scheme allows CR to use half of the frame to transmit data while using the left half to help PU with cooperative transmission. The proposed power allocation based on the scheme can make CR achieve higher rate without influencing PU. Simulation results show thin compared with the conventional non-cooperative communication, the proposed scheme can make improvements on the rates of both PU and CR.
