Title
Decision Feedback CIR and CFO Estimation Algorithm for FBMC/OQAM System
Abstract
FBMC/OQAM is regarded as an alternative modulation scheme for OFDM. The classical Channel Impulse Response (CIR) and Carrier Frequency Offset (CFO) estimation methods based on scattered pilots in OFDM system cannot be directly applied to FBMC/OQAM system, because of the intrinsic pure imaginary interference. Traditional methods in FBMC/OQAM use scattered pilots and auxiliary pilots to estimate CIR and CFO, which increase system overhead and transmitter complexity. In this paper, we present a novel CIR and CFO estimation method with scattered pseudo-pilots and iterative decision feedback structure. Simulation results show that the proposed method can estimate the CIR and CFO accurately in frequency selective channel and BER performance is better than the estimation method based on auxiliary pilot. Moreover, time-frequency resources that used for pilot in the proposed algorithm is only half of auxiliary pilot based method.
