my_fft_fixed_point

说明：  在子图像上面添加标题的matlab函数 (A function to place a title above all subplots)

用阵列光电传感器实现空间窄带陷波功能时，采用右图所示的空间权重结构：共有N=2M+1个敏感元件，各敏感元件宽为w，间距为p，中心处敏感元件的权重为+2M，其他2M个敏感元件的权重皆为-1。求此权重函数的傅立叶变换及空间功率谱，并绘图说明当N=7，p=1mm，w=1/３mm时的空间功率谱的零点特征及其应用意义。(With a photoelectric sensor array to achieve narrow-band notch function space, with the weight shown on the right of the space structure: a total of N = 2M+1 a sensitive element, the sensor width w, spacing p, the center of the sensitive components of weight+2 M, 2M a sensitive element of the other weights are all-1. This function find the Fourier transform of the weight and space power spectrum, and the drawing shows that when N = 7, p = 1mm, w = 1/3mm space power spectrum at zero characteristics and application significance.)

GMSK BER AWGN BCH code

说明：  用PSO求解函数的最大值，有图形界面，适合初学者学习。(a function to find the Max.Value using PSOA, good structure and nice interface.)

核磁共振成像的基本原理， 核磁共振成像仪中的接收机单元， 磁共振图像降噪的内容。 (The basic principle of magnetic resonance imaging, MRI of the receiver unit, magnetic resonance image noise content.)

说明：  可以实现微网逆变器VF控制。测试通过可以使用。(It can be realized VF)

You can use it to simulation OFDM in BPSK,QPSK and 8PSK in AWGN channel.You can see the symbol error rate and bit error rate from these simulation.

在程序中将不相干的一些数据进行处理,并用mschart绘制出直观图出来(procedures will be irrelevant in some of the information processed and used mschart drawn out direct-viewing chart)
