在MATLAB中用Goertzel算法（先用FFT算法，再用goertzel算法，）仿真DTMF的产生与检测的程序。应用于双音多频信号的产生与检测。(in Goertzel algorithm using MATLAB (first using FFT algorithm, reuse goertzel algorithm) simulation DTMF detection with the selection process. Used DTMF signal detection with the selection.)

说明：  利用伪随机序列作为发送信号，经过信道，产生了频偏和相位偏移，利用数字锁相环的原理实现对信号的频率估计和相位估计，实现信号的载波同步。(The frequency offset and phase offset are generated by using pseudo-random sequence as the transmitting signal through the channel. The frequency estimation and phase estimation of the signal are realized by using the principle of digital phase-locked loop, and the carrier synchronization of the signal is realized.)

此程序用于OFDM与FBMC的对比，详细描述了UFMC系统的发送和接收的仿真实现过程，并对比相同系统参数下的OFDM系统，发现FBMC系统的优势。(This program is used for OFDM and FBMC contrast, describing the detail of UFMC transmitter and receiver simulation process, and comparing the the OFDM system under the same system parameters to verify the advantages of FBMC system.)

说明：  MIMO系统由于在空间中具有多个发送和接收天线，因此其信道模型也具有其特有的复杂性。尽管具有这种复杂性，对MIMO信道进行建模仍然十分必要。(Because MIMO system has multiple transmit and receive antennas in space, its channel model also has its own complexity. Despite this complexity, it is still necessary to model MIMO channels.)

void swap1(int x, int y) //值传递 void swap2(int *px, int *py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用(void swap1(int x, int y) //值传递 void swap2(int*px, int*py) //指针传递 void swap3(int &x, int &y) //引用传递 的使用)
