A New OFDM-OQAM Channel Estimation Method

It is not necessary for the OFDM /OQAM system to insert the guard interval,with a higher spectral efficiency can be resistance to inter-symbol interference and inter-channel interference characteristics at the same time,the legacy OFDM system has become an alternative. This paper is based on the new pilot sequence structure and the system features of the OFDM / OQAM,the system analyzes the correlation between adjacent sub-carriers,a new channel estimation method based on the pilot sequences structure,by calculating the adjacent the correlation coefficient of subcarriers reduce the interference and noise on the channel estimation. The simulation results show that the structure of this pilot will help reduce the impact of noise on the channel estimation to improve the performance of the system.
