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.)

随着蜂窝移动通信市场的巨大发展，下一代通信将是移动多媒体通信。这种情况产生了一个问题，如何对语音信源以外的多媒体信源进行功率控制。在探讨这个问题上，我们引入微观经济学中的数学模型和概念以及博弈论理论。在本文中，电话的通话质量被称为“效度”，对于一个CDMA电话通信的分布式功率控制被看作是一个‘非协作的博弈’。(CDMA mobile communication system is a technology which will be used in the next-generation communications system, so wideband CDMA technology has been unprecedented attention, and a large number of improved algorithm to improve the performance of CDMA system has emerged in its various research on key technologies.)
