Abstract :
A new packet-combining (PC) scheme based on packet-level coding is proposed. Through feedback, the receiver controls the transmitting node to encode (XOR) source packets. Efficient methods to combat even-errors among erroneous packets are investigated. Also proposed is a reduced-complexity decoder. Numerical results show that the proposed scheme can significantly outperform the ARQ scheme or PC without coding.
