Abstract
Robust high date rate mobile communications have several challengers.Transmission of
high rate information typically experiences higher delay spread in mobile environments
Furthermore,high mobility introduces time-variations which can make the link less reliable.
Orthogonal Frequency Division Multiplexing(OFDM) is suitable for high delay spread application.However,performance of OFDM systems ,is affected by channel estimation,timing synchronization and mobility.Timing synchronization becomes challenging in high mobility applications as power delay profile of the channel can change rapidly due to th sporadie birth and death of the paths..........
简介:Timing synchronization and ICI mitigation for pilot-aided OFDM mobile systems
