- W2800896688 abstract "Due to their low delay and complexity, short length codes are attractive for use in wirelesscommunication systems. Also, achieving low complexity, high performance and low decoding latencies, is the keyrequirements of low-density parity-check (LDPC) code because these provide more reliable code for manyapplications. In this paper, a novel method was proposed to construct a short length code based on theconvolutional encoder and LDPC decoder. In this code, delay and computational complexity of encoding anddecoding were significantly reduced compared to other LDPC codes when they were simulated at the same lengthand code rate. The main contribution of this work was to design a code with low time delay and low computationcomplexity while having an improved bit error rate (BER) performance. Complexity and latency were reduced byusing a convolutional technique for the encoding and by providing an improved parity-check matrix for thedecoding. The codes were simulated over additive white Gaussian noise (AWGN) channel using differentmodulation schemes. Theoretical analysis denoted that the encoder and decoder may offer advantages in terms oflatency and complexity, while simulation results have showed that the proposed code achieved an improvementover other LDPC codes that have the same length and code rates." @default.
