comsim's Introduction

数字通信2FSK调制/解调仿真

载波的频率和滤波器的参数设置不太合理，应考虑系统带宽等因素。

##List##

main.cpp
main.h - 各滤波器的冲击响应
f1.dat - '1'对应的载波
f2.dat - '0'对应的载波
bfp1.dat - 中心频率为f1 = 10kHz, 3dB带宽为2kHz的带通滤波器冲击响应
bfp2.dat - 中心频率为f2 = 40kHz, 3dB带宽为2kHz的带通滤波器冲击响应
lpf.dat - 截止频率为fc = 1kHz的低通滤波器冲击响应
tx.dat - 已调信号
tx_pn.dat - 信道输出信号
ch_outp1.dat - 上路解调信号
ch_outp2.dat - 下路解调信号
profile.m - 绘制各种波形
