Effect of Group Delay on Channel Estimation Performance in OFDM System

PP: 1037-1045
XIA LEI et al,
The OFDM (Orthogonal Frequency Division Multiplexing) channel estimation technologies are discussed and researched in this paper. The effect of group delay on the channel estimation technologies of OFDM System is researched. After thorough theory analysis and simulation programs, the conclusion that under slow and flat circumstance, the effect of group delay on the channel estimation algorithms of OFDM System is considerably small has been made.
