OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

实现能量检测仿真，由main函数进行能量检测，psk_2实现BPSK调制，pdsnr计算出理论值，最后由main给出理论与仿真之间的画图比较。(Achieve energy detection simulation, the main function of the energy detection, psk_2 achieve modulation BPSK, pdsnr calculate the theoretical value, and finally given by the main draw between theory and simulation comparison.)

波束形成算法中一种变换形式的极坐标算法（与传统的极坐标算法不同）(Polardb is a modified version of the regular polar function.)

C语言与MATLAB接口编程实例，主要是一些C语言与MATLAB 接口的程序，希望对大家有用(C language MATLAB interface programming examples, some of the C language and MATLAB interface program, and hope to be useful)

good code Files: (see file headers, or type help file in MATLAB, for more info) README - this file trainEM_tree.m - function that takes a wavelet transform, a number of states, and a maximum number of iterations and returns HMT parameters. No convergence criteria is specified right now (easily fixed), it just runs a specified number of iterations (default 30).
