说明: 设计一个理想通信系统,实现信息字符流的传输。
发射器:
<1>将消息(字符串形式)编码成一个符号序列;
<2>用脉冲成形将串符号序列转变成模拟脉冲信号;
<3>将模拟脉冲信号调制到载波信号上。
接收器:
<1>对接收的信号进行采样;
<2>解调信号成基带信号;
<3>将信号恢复成字符串。(Design an ideal communication system, the realization information transmission of character flow.
Emitters:
< 1 > will news (string form) coding into a symbol sequence
< 2 > by using a pulse forming will string of symbols into a simulation pulse signal sequences
< 3 > will simulate the pulse signal modulation to carrier signal.
Receiver:
< 1 > of received signal sampling
< 2 > demodulation signal into baseband signal
< 3 > will signal back into a string.)
