Basic principals of digital quadrature coherent detection are described in this paper via interpolation method. Two implementations are presented, and the signal flow is analysed. The rejection effects to mirror frequencies are discussed and compared emphatically between the two implementations. Computer simulation is carried out. Both the theoretical analysis and simulation results make a good reference to engineering application.
