现有数字信号自动调制识别方法大多只适用于无记忆信号,如PSK、ASK、FSK信号等。将有记忆
信号(MSK信号)和无记忆信号一起考虑,提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统
计量作为特征参数,采用多层神经网络作为分类器。计算机仿真表明:当噪声采用高斯白噪声,并且信噪比大于
l5 dB时,识别率高于96% ;当信噪比不低于l0 dB时,识别率不低于90%。,Existing digital signal automatic modulation recognition

本课程设计完成了基带线路码产生电路的设计,数字基带信号的传输是数字通信系统的重要组成部分之一。在数字通信中,有些场合可不经过载波调制和解调过程,而对基带信号进行直接传输。为使基带信号能适合在基带信道中传输,通常要经过基带信号变换,这种变换过程事实上就是编码过程。本些课题实现了这样的编码过程。-This course is designed to use VHDL hardware descr iption language completed the base-band circuits hav
