General precoder design for mitigation of intercarrier interference in OFDM mobile systems

摘要

Orthogonal frequency division multiplexing(OFDM)is now widely applied for high-rate datacommunication systems.But one of the main draw-backs of OFDMis its sensitivityto frequencyshifts,which ruins the orthogonality of the subcarriers andin turn brings about the Intercarrier Interference(ICI)and the perfor mance of OFDMsystemcan beseriously degraded.Therefore,howto eli minate theICI and i mprove the perfor mance of systemis a keytechnique for OFDMsystems.Various techniques have recently been proposedto comba...
