NDLI: Packing additional bits into LDPC coded data

Content Provider	IET Digital Library
Author	Cai, Suihua Zhao, Shancheng Ma, Xiao
Abstract	In this Letter, the authors proposed a novel scheme, with neither extra transmission energy nor extra bandwidth, to transmit additional bits along with low-density parity-check (LDPC) coded payload data. At the transmitter, additional bits are first transformed into a random-like sequence, which is then superimposed onto the LDPC coded data, resulting in the transmitted sequence. At the receiver, a statistical learning-based algorithm is employed to detect the additional bits. Then the interference of the additional bits is removed and the payload data is recovered by the conventional LDPC decoder. Simulation results show that, for a (3,6)-regular LDPC code of length 8064, ten additional bits can be transmitted reliably with negligible effect on the reliability of the payload data.
