说明：  用MATLAB编写的svm源程序，可以实现支持向量机，用于特征分类或提取(MATLAB source code written using svm, support vector machine can be achieved for feature classification or extraction)

修改自pudn的fm_gui_v2.基于相位相关方法（傅里叶变化），可有效实现任意大小两图的位移、尺度变化、旋转量，并输出拼接结果(Modified pudn of fm_gui_v2. Based on phase correlation method (Fourier transform), which can effectively achieve the displacement of any size, the two figures, the scale changes, the amount of rotation, and outputs the result stitching)

mobility and that can readily coexist with HSPA and earlier networks. OFDM/OFDMA technology is introduced for the LTE downlink, supporting very high data rates of up to 300Mbps while Single-Carrier FDMA (SC-FDMA) is used in the uplink with data rates of 80Mbps possible. Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the
