We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

1、根据干扰总功率要求，在PSK调制信号带宽内产生单音干扰和多音干扰信号，并叠加到产生的信号源上。
2、将收到干扰的信号进行频率搬移到基带，然后通过匹配滤波器以及解调过程得到信息，统计误码率并与真实信息的解调误码率进行对比，评估音频干扰对PSK信号的干扰效果。
(1, according to the total power requirement of interference generated tone signal interference and multi-tone interference in the PSK modulated signal bandwidth, and superimposed on the signal generated by the source. 2, the received interference signal to a baseband frequency shift, and the information obtained by the matched filter and a demodulation process, statistical error rate BER and the true information demodulation comparison, evaluation of the PSK signal, audio interference interference effects.)
