摘要 针对放大转发协作通信系统中,中继放大功率倍数固定导致系统功率效率较低的问题,提出了一种低密度奇偶校验码(LDPC)编码的自适应调整放大倍数的放大转发算法,在保证一定的误码率要求的前提下,最大化地提高系统功率效率。仿真结果表明,在固定功率放大转发方案和自适应放大转发方案都满足给定误码率的条件下,后者能更加有效地利用系统功率。 Because the amplifier gain of relay node is fixed, the efficiency of power is not high for the amplify and forward scheme in user cooperation. An algorithm which can adaptively adjust the gain is presented in this paper. The adaptive scheme improves the utilization ratio of energy in the presence of the reliability requirement. Theoretical analysis and simulation results demonstrate that the adaptive algorithm takes advantage of power more efficiently than the traditional fixed scheme with the given error rate.
