该方案无需重新配置系统的参数，仅改变输入信号即可实现两输入或三输入的RZ/NRZ-DPSK格式逻辑异或门和RZ-OOK格式逻辑与门。

In the proposed scheme , it does not need to reconfigure the parameters of the system , only change the input signal , two or three input DPSK format logic XOR gate and RZ-OOK format logic AND gate can be realized .

此方案完全采用逻辑异或运算，因此编码和解码速度快。

The logical exclusion OR operation are fully applied to the scheme so coding and decoding speed is quick .

增加控制脉冲，可以提高逻辑异或门的性能，但同时，控制脉冲功率的增加也会使输出信号恶化，因此需要合理选择控制脉冲的功率。

In addition , the performance of XOR logic gate can be improved by additional control pulse . However , the increase of control pulse power would deteriorate the output signal , and then the control pulse power should be chosen properly .

还有另外一种逻辑操作叫做异或：当且仅当所有的成员为真时，结果才为假。

There 's another logic operation called exclusive OR , in which the compound sentence is false , not true , if and only if all the components are true .
