FPGA-based single-sideband modulation and demodulation system 基于FPGA的单边带调制解调系统
A Practical Single-sideband Modulation Method on High Power HF Transmitter 一种在大功率短波发射机上实用的单边带调制方式
The dissertation firstly introduce the system architecture and principle of the microwave photonic phase shifter based on the suppression of the optical carrier single-sideband modulation mode, verify the feasibility by experiments, point out the deficiencies of the scheme and propose the improved measure. 论文首先对基于抑制光载波的单边带调制方式的微波光子移相方案进行系统结构介绍和原理分析,并通过实验验证方案的可行性,指出了方案的不足,并提出了改进措施。
And two different schemes are proposed on the basis of DPMZM: 1. A microwave photonic phase shifter based on the suppression of the optical carrier single-sideband modulation mode. 2. 在DPMZM的基础上相应提出了两种不同的方案:1.基于抑制光载波的单边带调制方式(CS-SSB)的微波光子移相器。
