- Abstract:
- The OFDM/OQAM system has become an alternative to the traditional OFDM system because it does not need to insert a guard interval, has higher spectral efficiency, and can resist inter-symbol interference and inter-channel interference at the same time. Based on the new pilot sequence structure and Based on the system characteristics of OFDM/OQAM, the correlation between adjacent subcarriers of the system is analyzed, and a new channel estimation method based on the pilot sequence structure is proposed. By calculating the correlation coefficient of adjacent subcarriers, the interference and The influence of noise on channel estimation. The simulation results show that this pilot structure is beneficial to reduce the influence of noise on channel estimation, thereby improving the performance of the system.
