Abstract

This paper proposes a packet retransmission scheme with interference cancellation for OFDM systems based on the basic principle of spread spectrum technique. The proposed design orthogonally spreads packets in transmission-domain to separate the desired signal from the interferences. Almost without increasing complexity, it outperforms the conventional packet retransmission scheme.
