Estimating time and frequency under imperfect channel knowledge using ECM and SAGE algorithms in multi-relay cooperative networks

Abstract The OFDM system is popular due to its broadband capabilities, but because it employs the multicarrier concept, synchronization issues may arise. These errors are caused by the incompatibility of the transmitted and received signals. The performance of multiple relay cooperative systems is a...
