HHTsummary

OFDM信道估计程序。 该程序包可生成OFDM信号，可显示经衰落信道变化后的OFDM信号波形，且给出了LS，LMMSE多种信道估计算法。(OFDM channel estimation procedure. The package can generate OFDM signals can be displayed by the fading channel changes of OFDM signal waveforms, and gives the LS, LMMSE channel estimation algorithm for a wide range.)

说明：  估计随机信号的样本自相关序列。先以白噪声 为例(Random signal is estimated that the sample autocorrelation sequences. First used white noise as an example)

二维傅里叶变换,对图像进行二维傅里叶变换处理(Two-Dimensional Fast Fourier Transform The purpose of this project is to develop a 2-D FFT program "package" that will be used in several other projects that follow. Your implementation must have the capabilities to: (a) Multiply the input image by (-1)x+y to center the transform for filtering. (b) Multiply the resulting (complex) array by a real function (in the sense that the the real coefficients multiply both the real and imaginary parts of the transforms). Recall that multiplication of two images is done on pairs of corresponding elements. (c) Compute the inverse Fourier transform. (d) Multiply the result by (-1)x+y and take the real part. (e) Compute the spectrum.)

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)
