摘　　要：针对干扰近似估计(interference approximation method,IAM)算法中提高FBMC/OQAM系统信道估计性能方案中噪声对性能的影响较大的问题,通过对传统干扰近似估计—实时(interference approximation method-real,IAM-R)信道估计算法进行改进,提出了一种基于等效导频功率最小值最大化的导频设计信道估计方案。该算法在传统IAM-R算法的基础上,通过对两侧导频的重新设计,提高了等效导频的功率,进一步减小噪声对信道估计性能的影响。In the interference approximation method,the channel estimation performance in FBMC/OQAM system is mainly affected by noise. Through improving the existing interference approximation method-real channel estimation,this paper proposed a channel estimation method based on equivalent pilot power minimum value maximization in which both sides of the pilot redesigned. As a sequence,the equivalent pilot power was raised and the influence of noise on the channel estimation performance furtherly.
