Abstract
A microwave photonics based signal receiving device includes a signal generation module, a first Mach-Zehnder modulator, a dispersion module, a second Mach-Zehnder modulator, and a signal conversion module. The signal receiving device simplifies a structure of the signal receiving device by adopting quadrature demodulation. The signal receiving device demodulates a high-order modulation signal and flexibly adjusts a microwave carrier frequency.
