Abstract :
This paper investigates error control at the physical layer of a multicast network using low-density parity-check (LDPC) codes. Packets for transmission are encoded into LDPC codewords. A joint iterative message-passing scheme for decoding LDPC codewords at a receive node in the network is proposed to improve error performance. Also proposed is a split-codeword transmission to provide equal error protection for all transmitted packets. Density evolution analysis and some simulation results are also presented.
