Abstract (English): Based on the idea of cooperative relay，we proposed a system model that the secondary user assisted the primary user to transmit， and used the Lagrange dual-optimized power allocation algorithm based on decoding and forwarding for power allocation， which solved the problem of excessive interference caused by the secondary user accessing the primary user frequency band. The simulation results show that the proposed algorithm can greatly reduce the tnterference to the primary users under the premise of ensuring the normal communication of the secondary users， effectively increase the resistance of the primary user to the external environment and improve the system capacity of the primary user.

Abstract (Chinese): 基于协作中继的思想,提出一种组成次用户协助主用户传输的系统模型,用基于解码 转发的Lagrange对偶优化功率分配算法进行功率分配,解决了次用户接入主用户频段产生 的干扰过大问题.仿真结果表明,该算法在保障次用户正常通信的前提下,可大幅度降低对 主用户的干扰,即可有效增大主用户对外界环境的抵抗力,并提高主用户的系统容量. [ABSTRACT FROM AUTHOR]
