针对采用解码-转发(DF)协议的协作中继网络,提出了一种基于买者-卖者博弈的中继选择和功率分配策略,通过将用户建模为买者,可以以最大效用为标准选择最优中继和确定最佳的购买功率;将中继建模为卖者,可通过先市场后利润的功率价格调整策略获得最大的利润。(For the cooperative relay network using decode and forward (DF) protocol, a relay selection and power allocation strategy based on the buyer seller game is proposed. By modeling the user as a buyer, the optimal relay and the optimal purchasing power can be selected with maximum utility as the standard. The relay is modeled as a seller, and the profit can be achieved through the market after the first market. The power price adjustment strategy obtains the maximum profit.)

说明：  实现了谱估计的算法，Matlab实现了直接法、间接法和改进的直接法谱估计的功能。(Achieved a spectral estimation algorithm, Matlab implementation of the direct method, indirect method and direct method of spectral estimation to improve function.)

快速计算一维信号的塔式谱峭度图，选择谱峭度最大值区间，方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)

We first present the Hypothesis Selection Filter in a general setting. For a given image enhancement problem, suppose we have selected a set of image filters each of which is effective in improving the image quality for a certain type of content. Our objective is to combine the filter outputs to obtain an overall best quality result. In the following, we use upper-case letters to denote random variables and random vectors, and lower-case letters to denote their realizations.
