Packet Combining Scheme with Bit Oriented XORed of All Bits of Packet: An Idea

Abstract

Packet combining scheme is a well defined simple error correction scheme with erroneous copies at the receiver. The scheme fails to correct errors when errors occur in the same bit locations of the erroneous copies. In some earlier works, several schemes such as multiple packet combining scheme (MPC) and packet reversed packet combining scheme (PRPC) that will correct error if occurs at the same bit location of the erroneous copies, are studied. A combined protocol of PRPC and MPC that offers higher throughput and better correction capability is studied elsewhere. In an earlier work, a simple scheme of XORed based mini packet combining scheme that will correct error(s) at the receiver is studied. In this paper we study a new scheme of XORed based full packet combining scheme. While the earlier scheme fits to correct only single bit error, the proposed scheme will correct up to multiple bit error.
