Abstract

Recently, the Orthogonal Frequency Division Multiplexing Access (OFDM/OFDMA) based wireless transmission technology has been widely accepted by consumers. Frame Check Sequence (FCS) scheme was employed to enhance the reliability of OFDM/OFDMA systems. Since the padding overhead cannot be effectively avoided in OFDM/OFDMA when MAC frames are encapsulated. We propose a novel CRC based error correction scheme by utilizing the frame padding to carry extra segmented FCS information as much as possible; compared with legacy FCS scheme, our approach obtains a significant improvement in error detection and correction upon the first retransmission (2nd transmission). In addition, we demonstrate a significant performance improvement based on the mathematic analysis.
