中文摘要：
为了抵抗信道衰落以及提高频谱利用率，提出了在多信道多主用户的认知无线电网络中，次用户协作主用户通信的模型．同时基于实际情况中最大化主用户吞吐量的准则，建立了分配问题，通过理论分析，将该问题转化为数学中的指派问题，并根据匈牙利算法提出了分配次用户协作主用户通信的算法以及相应的次用户的接入机制．仿真结果表明，提出的次用户协作主用户通信机制能够较好地抵抗信道衰落，大幅提升主用户的吞吐量，从而提高频谱利用率．
英文摘要：
To oppose channel fading and improve spectrum utilization, a model of multi secondary users as- sist the primary users in a multi-channels cognitive radio network was proposed. Based upon the maximal throughput principle, an allocate problem was created. Through theoretical analysis, the allocate problem was transformed into the standard assignment problem （AP）, and a select algorithm basd on the Hungar- ian method was proposed. The simulation results show that the proposed relay mechanism can oppose the channel fading well and increase the throughput of the primary users significantly, thereby improve the spectrum utilization.
