在计算机上产生一组实验数据，首先产生一段零均值白噪声数据u（n）,令功率为 ，让u(n)通过一个三阶FIR：
得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形；
(2)得出真实功率谱密度 .
(3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。
(On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)

(eBook---CRC-Press)-Handbook-of-applied-Cryptogra
Cryptography has a long and fascinating history. The most complete non-technical account
of the subject is Kahn’s The Codebreakers. This book traces cryptography from its initial
and limited use by the Egyptians some 4000 years ago, to the twentieth century where it
played a crucial role in the outcome of both world wars.
