DDS实现AM调制、DSB调制【Matlab】【FPGA】【Vivado】【信号处理】【通信原理】【软件无线电】 一、为什么要调制 调制(modulation)就是对信号源的信息进行处理(低频),加到载波上(高频),使其变为适合于信道传输的形式。 无线电传输时,频率越高,波长越小,发射时需要的天线也越短。
1、基于Matlab的AM、DSB、SSB信号的调制摘要:调幅,英文是Amplitude Modulation(AM)。调幅也就是通常说的中波,范围在503-1060KHz。调幅是用声音的高低变为幅度的变化的电信号。 距离较远,受天气因素影响较大,适合省际电台的广播。DSB(Double Side Band),在通信领域代表调制的一种方式,叫双边带调制。抑制载波双边带...
