Covariance matrix decomposition is employed in the estimation, based on the assumption that the spectral of echoes from weather targets is subject to Gaussian distribution.
39349 通过理论分析，推导出雷达回波的协方差矩阵具有范德蒙结构特性，进而将用于谱矩估计的代价函数转化为类傅里叶变换结构，然后进一步通过快速傅里叶变换和高斯加权滑窗计算代价函数，实现快速的谱矩估计。 Theoretical analysis suggests that the covariance matrix of the echoes conforms to the Vandermonde structure, thus the cost function for covariance-matrix-based spectral moment estimation can be interpreted by a DFT-type matrix. The cost function for fast spectral moment estimation is then computed by Fast Fourier Transform and Gaussian weighted sliding window.

And there is no compromise of estimation performance under a wide spectral width situation with this reduced computational complexity method.

We formulate the interaction between a cellular user equipment(CUE) and multiple D2 D user equipments(DUEs) to be an one-leader-multiple-follower Stackelberg game. An interference pricing mechanism is introduced to investigate the competitive relationship between the CUE and DUEs, and an exact potential subgame is designed to model the cooperative relationship among DUEs.
