Abstract: Receiver in-phase/quadrature (IQ) imbalance caused by imperfect analog receiver front end can rapidly degrade system performance in Nyquist-subcarrier-modulation (Nyquist-SCM) direct detection scheme. These imbalances, including IQ skew, IQ gain and phase imbalance, become increasingly important… read more here.

Abstract: Abstract Nyquist-SCM signal after fiber transmission, direct detection (DD), and analog down-conversion suffers from linear ISI, nonlinear ISI, and I/Q imbalance, simultaneously. Theoretical analysis based on widely linear (WL) and Volterra series is given to… read more here.
