Low complexity estimation of carrier and sampling frequency offsets in burst-mode OFDM systems

摘要

Residual carrier frequency offset (CFO) and sampling frequency offset (SFO) in orthogonal frequency-division multiplexing (OFDM) transmission result in loss of orthogonality between the subcarriers, which severely degrades system performance. This makes effective CFO and SFO estimation methods essential for such systems. In this work, we address the joint estimation of CFO and SFO, focusing on burst-mode OFDM communications scenarios.
