摘要 K分布形状参数的M估计器是一种估计精度比较高的估计器,2005年由郝程鹏提出,2007年得到了进一步的改进。该文对2007年的改进的M估计器进行了进一步的改进,省去了其中的一些中间环节,仿真实验证明,该文方法显著提高了估计器的精度与效率。 M-estimator is a new estimator presented by Hao Cheng-peng in 2005,which possesses higher accuracy in the estimation of shape parameter of K-distribution and is enhanced in 2007.In this paper,a further enhanced M-estimator is proposed based on the enhanced M-estimator in 2007,in which some original middle procedures are omitted.The simulation results show that the estimation accuracy and efficiency both increase dramatically.
