本代码介绍了OFDM/OQAM 多径信道下，理想信道估计的系统仿真，给出了不同信噪比下的ber性能。介绍了多载波系统的均衡。(This code describes the OFDM/OQAM multipath channel, system simulation, ideal channel estimation, given the ber performance under different signal to noise ratio. The equilibrium of the multi-carrier system.)

QPSK调制matlab程序 包括基带成型滤波器 （升余弦滤波器）(QPSK modulation Matlab procedures including baseband shaping filter (or cosine filter))

通过调用计算雷达的信噪比，对比雷达在三咱不同雷达截面积下的信噪比，从而分析不同雷达截面积下信噪比情况是如何的，得出相应结论(Calculated by calling the radar signal-to-noise ratio than radar signal-to-noise ratio in the three Zan different radar cross section, which is how to analyze the signal-to-noise ratio in a different radar cross section, draw the corresponding conclusions)

matlab界面编程中的实现可选的子界面！ 就像VC++的MFC中的Table空间，解决你的复选问题！(The matlab interface programming realization optional sub-interface! Table space like VC++ the MFC solve your check!)

车子里程记录表，用GPS经纬度计算距离，驱动LCD显示(Car mileage record sheet, calculate the distance by GPS latitude and longitude, driven LCD display)

维纳滤波与功率倒置阵比较,应用环境为GPS信号抗干扰(comparing weiner filer and power inversion array)

GMSK的调制解调原理分析，包含MATLAB程序代码，代码后有注释(GMSK modulation and demodulation principle analysis, including MATLAB program code, code after annotations.)

说明：  对于新手调试入手很快,通过32单片进行通信控制,及算法运算给(For beginners, debugging starts very quickly, communication control is carried out through 32 single chip, and arithmetic operation is given to them.)

说明：  产生FM信号，并利用锁相环的载波同步对信号进行跟踪并解调(FM signal is generated, and the carrier synchronization of PLL is used to track and demodulate the signal)
