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

这是一本关于Windows下内存映射文件相关内容的书籍， 通过它可以操作文件，它的速度是I/O操作的20倍，及其适合大文件的操作(This is a book about Windows memory mapping document of relevant books, through which it can file, its speed is I/O operation20 times, and is suitable for large files )

本程序模拟了一个2DPSK发送和接受的完整过程，差分编码采用模2加的方式得到，本次实验采用的是相移键控的方法得到发送信号，2DPSK信号最常用的解调方法有两种，本次实验采用的是极性比较法，先通过2PSK相干解调器，再经过码（反）变换器得到基带信号。 (This program simulates a 2DPSK sending and receiving complete process, differential coding is completed by modulo-2 addition； the experiment using the phase shift keying method to send signals.this experiment is the polarity comparison method,firstly go through the 2PSK coherent demodulator and then pass through code (trans) converter to obtain a baseband signal.)
