This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...
Fig 1. In this view of the architecture of an optical analyzer, the coherent reference receiver serves as the optical front end to the digitizer, taking as inputs two single-mode fibers, one carrying ...
