无线PPT遥控发送电路设计

这是一个2DPSK调制电路，2DPSK离不开二进制相移键控2PSK。

首先对二进制数字基带信号进行差分编码，将绝对码表示二进制信息变换为用相对码表示二进制信息，

然后再进行绝对调相，从而产生二进制差分相位键控信号.

This is a 2 DPSK modulation circuit, 2 DPSK cannot leave the binary phase shift keying PSK 2.

First of all to the binary number baseband signal difference code. It will be absolutely code said information transform with the relatively for binary code said binary information,

And then the absolute phase-modulation, resulting in a binary differential phase keyed signal.
