利用matlab，产生具有三个频率的跳频信号(the generation of jump-frequency signal)

采用复小波变换提取小波脊线，可较好识别频率(Using complex Wavelet transform Wavelet Ridge can better identify the frequency)

说明：  直线偏移代码，已知多边形顶点坐标，可以将多边形各边沿其法线方向平移距离然后得到新的多边形顶点。(Linear shift code, known polygon vertex coordinates, can be the edge of the polygon shift its normal direction and then get a new polygon from the vertex.)

比较全的捷联惯导程序，并且利用数据库存储陀螺和加速度输出，比较简便，经典的惯导程序(Compare the whole of the SINS program, and use the database to store the gyro and accelerometer output is relatively simple and classic INS procedures)

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
