Additional insight on SAGE-based carrier and residual frequency offset estimations in OFDM systems

Insight on estimations of the space-alternating generalized expectationmaximization (SAGE)-based carrier É and residual õ frequency offset with the inclusion of inter-carrier interference (ICI) power using Cramer-Rao's lower bound (CRLB) theorem and a linear model method is given. Additional simulation results are given. Detailed discussions are presented
