仿真了用于MIMO雷达的OFDM Chirp波形的自相关函数和互相关函数，便于进一步优化OFDM Chirp波形，使互相关和自相关性能接近正交波形的性能，从而提高雷达目标检测性能。因为匹配滤波相当于一个互相关器。附有所仿真波形的参考文献，波形设计见本人之前上传的文件(this matlab program simulate the correlation function of ofdm chirp waveform,so that reader can optimizing design new ofdm chirp waveform.from the simulation results we see that the correlation performance are not well enough,so we have to optimize the ofdm chirp.there is reference of my simulation.)

DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)
