摘要
A Variable Amplitude Auxiliary Pilot (VAAP) channel estimation scheme for the FBMC (Filter Bank Multicarrier) is put forward, which adds the auxiliary items in the AP positions directly to the pilots and fills the known data into the AP positions to solve the problem of excessive power of the auxiliary items in the conventional AP method. Theoretical analysis and simulation results demonstrate that compared with the Code Auxiliary Pilot (CAP) method and Double Auxiliary Pilot (DAP) method, when applying a single AP, the presented scheme can achieve a higher spectrum efficiency and reduce the power of AP positions effectively with no influence of the BER (Bit Error Rate) and it is second only to the AP method in computational complexity. By adopting the dual tunable AP, our proposed scheme can further improve the performance of the estimation accuracy and BER. © 2020, The Editorial Board of Journal of Xidian University.
