“…These protocols have been combined with channel codes to construct a more efficient way of cooperation known as coded-cooperative. Various codedcooperative schemes have been presented in literature such as low density parity check (LDPC) codes [4,5], turbo codes [6,7], polar codes [8][9][10] and Reed-Muller (RM) codes [11,12].…”

This paper proposes a distributed RS coding scheme which is comprised of two different ReedSolomon (RS) codes over fast Rayleigh fading channel. Practically in any distributed coding scheme, an appropriate encoding strategy at the relay plays a vital role in achieving an optimized code at the destination. Therefore, the authors have proposed an efficient approach for proper selection of information at the relay based on subspace approach. Using this approach as the proper benchmark, another more practical selection approach with low complexity is also proposed. Monte Carlo simulations demonstrate that the distributed RS coding scheme under the two approaches can achieve nearly the same bit error rate (BER) performance. Furthermore, to jointly decode the source and relay codes at the destination, two different decoding algorithms named as naive and smart algorithms are proposed. The simulation results reveal that the advantage of smart algorithm as compared to naive one. The proposed distributed RS coding scheme with smart algorithm outperforms its non-cooperative scheme by a gain of 2.4-3.2 dB under identical conditions. Moreover, the proposed distributed RS coding scheme outperforms multiple existing distributed coding schemes, making it an excellent candidate for the future distributed coding wireless communications.

“…Cooperation technology [11] is one of the most effective ways to enable the single-antenna devices to enjoy the spatial diversity of MIMO system, which can be traced back to the relay channel proposed by Cover and Gamal in 1979 [12]. In the half-duplex mode, the common cooperation schemes include amplify-and-forward (AF) [13,14], decode-and-forward (DF) [15], coded cooperation [16], and quantise-andforward (QF) [17,18]. SWIPT-based cooperation technology combines SWIPT technology and cooperation technology.…”

To achieve reliable and green communication in the internet of things (IoT) networks, the authors extend the traditional half-duplex quantise-and-forward (QF) cooperation into the simultaneous wireless information and power transfer (SWIPT) regime. This study investigates the achievable rate of the SWIPT-based half-duplex QF cooperation with the channel state information available only at the receivers. The source and destination are provided by the external power supply and the relay simultaneously implements the information transmission and the energy harvesting by SWIPT technology with the powersplitting protocol. The achievable rate of the proposed system over the additive white Gaussian noise channels is analysed and further maximised by optimising the power-splitting factor. Furthermore, the expected rate of the proposed system over the slowfading channels is analysed. Theoretical analysis and simulation results show that the achievable rate or expected rate of the SWIPT-based QF cooperation is obviously superior to that of the SWIPT-based amplify-and-forward or SWIPT-based decodeand-forward cooperation. Meanwhile, the SWIPT-based QF cooperation can achieve similar performance to the traditional QF cooperation when the external power supply at the relay is not provided.

“…The short length channel code such Reed-Muller (RM) code has been recently utilised in the coded-cooperative scenarios that not only yields better BER performance but also offered low complexity in both encoding and decoding processes [7]. Furthermore, another short length RM-coded cooperative scheme based on multiple relays is designed for vehicular ad hoc networks in the literature [8].…”
