针对干扰近似估计(interference approximation method，IAM)算法中提高FBMC/OAQM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 order to improve the performance of FBMC / OAQM system channel estimation in interference approximation method (IAM) algorithm, the influence of noise on performance is greatly affected. By using the traditional interference approximation method-real (IAM- R) channel estimation algorithm is improved, a pilot design channel estimation scheme based on the maximization of the equivalent pilot power minimum is proposed. Based on the traditional IAM-R algorithm, this algorithm improves the power of the equivalent pilot by redesigning the pilot on both sides to further reduce the impact of noise on channel estimation performance.
