This paper investigates non-binary low-density parity-check (LDPC) erasure correcting codes suitable to guarantee reliable transmission in wireless communications systems. In particular, irregular repeat-accumulate (IRA) codes are considered, characterized by linear-time encoding complexity. The performance of non-binary IRA codes is compared with their binary counterparts on the packet erasure channel...
Non-binary LDPC codes are now recognized as a potential competitor to binary coded solutions, especially when the codeword length is small or moderate. More and more works are reported with good performance/complexity tradeoffs, which make non-binary solutions interesting for practical applications, such as 4G-wireless systems or DVB-like systems. In this paper, we show that proposing non-binary LDPC...
In this paper the linear block code decoder is constructed by neural network. The neural network will be adapted for a single-bit error. Each layer of a neural network will simulate a linear block code decoder stage. The syndrome generator, the error detection, and the error correction stages of the linear block code decoder will be simulated by the proposed neural network.
In this paper, we investigate the application of nonbinary low-density parity-check (LDPC) cycle codes over Galois field GF(q) to multiple-input multiple-output (MIMO) channels. Two types of LDPC coded systems that employ either joint or separate MIMO detection and channel decoding are considered, depending on the size of the Galois field and the modulation choice. We construct a special class of...
In this paper, we investigate the application of non- binary low density parity check (LDPC) codes over Galois field GF(q) for both single-input single-output (SISO) and multiple- input multiple-output (MIMO) fading channels using higher order modulations. As opposed to the widely studied binary systems that employ joint detection and channel decoding, we propose a nonbinary system where optimal signal...
