Keywords: Joint network coding and LDPC decoding Two-way wireless relaying channel Wireless cooperative networks a b s t r a c t In this paper, we investigate the joint design of channel and network coding in bi-directional relaying systems and propose a combined low complexity physical network coding and LDPC decoding scheme. For the same LDPC codes(More)
—In order to improve broadcasting efficiency in LTE-A system, a novel HARQ scheme with network coding (NC) technology is presented in this paper. The implementation level of XORing NC is selected based on LTE system, and an XORing NC Combined (XNCC) strategy is developed to perform combined retransmission. The main idea of proposed scheme is to retrans-mit(More)
—The extreme value theory and the assumption that lattice orthogonal frequency division multiplexing (LOFDM) signal converges weakly to a Gaussian random process are employed to derive peak-to-average-power ratio (PAPR) in LOFDM systems. Two complementary cumulative distribution functions (CCDF) of LOFDM system with equal and unequal subcarrier power(More)
