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.)

psk31_9b_12a
PSK31 Model with Symbol Timing and Carrier Recovery(This model implements a communication standard known as PSK31. The transmit portion of the model can either synthesize the PSK31 signal, or use real world signals that were captured as Wave files.
The receiver features include: Automatic Frequency Control, Automatic Gain Control, Symbol Timing recovery with a fractionally spaced Farrow interpolator, Decision Directed Carrier Phase Lock Loop, dbsk or dqpsk demodulation with FEC.
References are provided in the Model.)
