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.)

Introduction_to_Smart_Antennas_C._A._Balanis_P
In recent years a substantial increase in the development of broadband wireless access technologies
for evolving wireless Internet services and improved cellular systems has been observed [1].
Because of them, it is widely foreseen that in the future an enormous rise in traffic will be experienced
for mobile and personal communications systems [2]. This is due to both an increased
number of users and introduction of new high bit rate data services. This trend is observed for
second-generation systems, and it will most certainly continue for third-generation systems.
The rise in traffic will put a demand on both manufacturers and operators to provide sufficient
capacity in the networks [3]. This becomes amajor challenging problem for the service providers
to solve, since there exist certain negative factors in the radiation environment contributing to
the limit in capacity
