In order to suppress the imaginary intrinsic part interference of OFDM/OQAM system in radio channel, a new pilot design approach is proposed. The new design approach can suppress the intrinsic imaginary interference in quasi-stationary channel and reduce the pilot peak power due to sparse data forms. This paper analyzes the reason why the imaginary intrinsic interference produces in the PLC (power line communication) channel and the new pilot eliminates the imaginary intrinsic interference.

Compared with the pilot design of OFDM/CP,OFDM/OQAM system, it is verified that the new pilot design approach is better than OFDM/CP ,IAM-R,IAM-I and almost the same as IAM-new under MATLAB simulation platform in the PLC channel with the same channel estimation and equalization mode.
