DPSK modulation DPSK调制
Besides, the limitation of RZ-DPSK regeneration utilizing self-phase modulation is discussed. The initial conditions using four-wave mixing to achieve regeneration is given.
同时对于RZ - DPSK信号，研究了利用自相位调制实现再生的局限性，给出了利用四波混频实现再生的初始条件。
To cope with the problem of phase shifts caused by different propagation paths (especially in HF links), the modulation is done in differential phase shift keying (DPSK).
为了克服由多径传播造成的相移失真难题(特别是在HF链路里)，调制采用差分相移键控(DPSK)来完成。
Firstly, this thesis analyzes the transmission characteristics of HF channel, and fixes on the system modulation scheme 2dpsk, according to the comparison of ASK, FSK and PSK (DPSK).
首先，本文分析了短波信道的传输特性，并通过比较A SK、FSK和PS K (DPSK)几种调制方式的特点，确定了2dpsk为系统的调制方案。
