“…Moreover, a genetic algorithms was developed by Said Nouh et al [40] to decode codes with systematic block, in order to gain low intricacy for decoding threshold, as well as via polynomial encoding for cyclic codes. Many published studies exist that have described methods developed for coded DF protocol, but existing works in [33], [41], [42] employ only some of the components, particularly using LDPC code. In this paper, we propose a comprehensive system model using LDPC code for DF relay protocol analysis.…”

Decoding high complexity is a major issue to design a decode and forward (DF) relay protocol. Thus, the establishment of low complexity decoding system would beneficial to assist decode and forward relay protocol. This paper reviews existing methods for the min-sum based LDPC decoding system as the low complexity decoding system. Reference lists of chosen articles were further reviewed for associated publications. This paper introduces comprehensive system model representing and describing the methods developed for LDPC based for DF relay protocol. It is consists of a number of components: (1) encoder and modulation at the source node, (2) demodulation, decoding, encoding and modulation at relay node, and (3) demodulation and decoding at the destination node. This paper also proposes a new taxonomy for min-sum based LDPC decoding techniques, highlights some of the most important components such as data used, result performances and profiles the Variable and Check Node (VCN) operation methods that have the potential to be used in DF relay protocol. Min-sum based LDPC decoding methods have the potential to provide an objective measure the best tradeoff between low complexities decoding process and the decoding error performance, and emerge as a cost-effective solution for practical application.

“…The information capacity gain of a wireless system can be increased by employing multiple transmit and/or receive antennas in a communication system [1][2][3][4][5]. Space-time coding lead to an increase in both bandwidth efficiency and reliability of wireless communication channels by combining spatial and temporal diversity [6].…”

Abstract: Inthis paper, two hybrid concatenated super-orthogonal space-time trellis codes(SOSTTC) applying iterative decoding are proposed for flat fading channels. Theencoding operation is based on the concatenation of convolutional codes,interleaving and super-orthogonal space-time trellis codes. The firstconcatenated scheme consists of a serial concatenation of a parallelconcatenated convolutional code with a SOSTTC while the second consists ofparallel concatenation of two serially concatenated convolutional and SOSTTCcodes. The decoding of these two schemes is described, their pairwise errorprobabilities are derived and the frame error rate (FER) performances areevaluated by computer simulation in Rayleigh fading channels. The proposedtopologies are shown to perform better than existing concatenated schemes with aconstituent code of convolutional andspace-time codes in literature.

“…This scheme is divided into block codes and convolutional codes [2], [3], [4]. FEC Convolutional Codes (FEC-CC) were introduced by Elias in 1955 as an alternative to the class of block codes and they are widely used in many applications such as mobile communication, digital video, and satellite communication to achieve reliable data transfer [5], [6], [7].…”

Abstract-ForTransmission burst errors; data decoding complexity and jitter are identified as key factors influencing the quality of service of RTAs implementation over wireless transmission media. This paper reviews FEC-CC as one of the most commonly used algorithm in Forward Error Correction for the purpose of improving its operational performance. Under this category, we have analyzed various previous works for their strengths and weaknesses in decoding FEC-CC. A comparison of various decoding algorithms is made based on their decoding computational complexity.
