The BP Network for Carrier Frequency Offset Estimation in OFDM-Based WLANs

摘要

This paper presents an efficient carrier frequency offset (CFO) estimation algorithm for the orthogonal frequency-division multiplexing (OFDM)-based wireless local area networks (WLANs) which adopts the IEEE 802.11 standardization. This algorithm adopts the BP network with the orthogonal projector for the fast adaptive CFO estimation. Numerical results are presented to demonstrate the effectiveness of the proposed algorithm.
