The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed 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

printScreenaprintFigure
matlab的getframe有时候并不能截取画出来的3D图像(而是截取出一个空坐标系).该程序用matlab调用windows的截图功能, 真正实现了原封不动的截图.(但是耗时会长一点). 使用时, 先把文件夹添加到matlab的路径下即可.文件夹中有两个功能略有不同的函数printScreen是截取整个屏幕, printFigure是截取整个屏幕后挖出当前的Figure窗口中的内容.(matlab does not intercept the getframe sometimes drawn 3D images (but the interception of an empty frame) The procedures used to call matlab windows screenshot function, truly untouched screenshot. (but a little time consuming president ) When using, first add a folder to the matlab' s path. folder has two functions is slightly different function printScreen intercept the entire screen, printFigure dug up the entire screen after interception current Figure window content.)
