调制信号的波形及其功率谱。。。很好用。。(The modulated signal waveform and the power spectrum)

说明：  三种常用的雷达图像成像算法，希望大家多多支持。(Three commonly used imaging method for radar image, hope you can enjoy.)

实现2PSK系统的matlab仿真以及误码率分析( Achieve 2PSK system matlab simulation and analysis of bit error rate )

说明：  本程序用于实现求解并绘制正弦信号功率谱密度的功能(procedures used to achieve the solution and the mapping of sinusoidal signal power spectral density function)

matlab example shows you can work that easily.

说明：  用于广播系统发射机的数字中频调制采用64QAM的方式，使用matlab中的altera dsp builder实现。(64QAM modulator, used in broadcast system digital IF modulation.)

信号在采集和输送过程中往往会参杂着噪声和干扰，将自适应神经网络与信号处理结合起来，采用最小均方（LSM）算法设计的线性自适应滤波器将信号中的杂波成分滤除。用matlab进行仿真,证实线性自适应滤波器具有良好的滤波功能。(Signal acquisition and delivery process often mingled with the noise and interference, the adaptive neural network combined with signal processing, with a minimum mean square (LSM) linear adaptive filter algorithm designed to signal noise filter components In addition. Using matlab simulation confirms linear adaptive filter has a good filtering.)

Code for obtaining Center of math of polygon. enjoy it.
