While the partial power training sequences is used for synchronization in Orthogonal Frequency-Division Multiplexing (OFDM) system
the received data signals will be interfered by the training sequences.we give a method for suppressing the interference caused by the training sequence.Especially we focus on only one OFDM symbol in a packet transmission.Both theoretical and simulated results of the above technique are presented under indoor multipath Rayleigh fading channel.It is shown that the better BER performance can be achieved as compared with no separation
and only one OFDM symbol can accomplish user data communication.
