“…As an advantage, a near-capacity code design can be found by employing EXIT charts without performing time-consuming Monte-Carlo simulations. EXIT charts can also be used for finding powerful codes exhibiting guaranteed convergence for a given channel [76]. Specifically, near-capacity codes have been successfully designed by applying an EXIT-chart-based technique, for example in [30], [61], [77].…”

Abstract-In this tutorial, the design procedure of nearcapacity channel code design invoking non-binary EXtrinsic Information Transfer (EXIT) charts is illustrated by using design examples of Irregular Concatenated Coding Arrangements (ICCAs) relying on Irregular Convolutional Codes (IrCCs). More specifically, in order to benchmark the near-capacity design examples, both the capacity and the Outage Probability (OP) of the Continuous-input Continuous-output Memoryless Channel (CCMC), of the Discrete-input Continuous-output Memoryless Channel (DCMC) as well as of the Differential Discreteinput Continuous-output Memoryless Channel (D-DCMC) are characterised. Furthermore, the EXIT-chart aided near-capacity design principles are illustrated by detailing the design process of three characteristic prototype schemes, which represent the family of coherent and non-coherent detection based systems as well as Multi-Input Multi-Output (MIMO) systems, respectively. Moreover, the beneficial application of the EXIT-chart based design principle is also demonstrated in the context of cooperative systems using a specific distributed MIMO prototype scheme.

“…2, at the source of the four-terminal successive relaying aided network, we use a three-component serial concatenated IRCC-URC-STC scheme, where the IRregular Convolutional Code (IRCC) [29], [30] and Unity-Rate Code (URC) [31] are employed to facilitate the near-capacity performance on the end-to-end link, as discussed in [32]- [34], and the Space-Time Code (STC) is used to achieve spatial diversity gains and/or coding gains. On the other hand, at both of the two relays, the same two-component serial concatenated IRCC-STC scheme is employed for the successive relaying aided network considered in this contribution, where the IRCCs at the relays may have different coding rates and weighting coefficients, and will assist us in attaining a near-capacity performance, as in [22].…”

Abstract-In this paper, we develop a capacity-approaching Cooperative Space-Time Coding (CSTC) scheme employing irregular design for a twin-relay aided network as an extension of our previous work cast in the context of a half-duplex singlerelay-aided network. For the sake of recovering the multiplexing loss imposed by a half-duplex three-terminal network, we employ a successive relaying protocol in this paper, where an additional relay node is activated. Hence, in order to design a near-capacity coding system, first the capacity and the achievable informationrate of a specific space-time coding aided scheme are quantified for the successive relaying aided channel. More specifically, the cooperative space-time codes employed at the source and the relays are jointly designed with the aid of EXtrinsic Information Transfer (EXIT) charts for the sake of high-integrity operation at Signal-to-Noise Ratios (SNRs) close to the corresponding successive relaying channel's capacity. Furthermore, unlike in the halfduplex single-relay based system, the destination node performs frame-by-frame Successive Interference Cancellation (SIC) aided iterative detection, in order to mitigate the efforts of multipleaccess interference. Finally, our numerical results demonstrate that our proposed Irregular Cooperative Space-Time Coding (Ir-CSTC) scheme is capable of near-capacity operation in the successive relaying aided network, which is an explicit benefit of our joint source-and-relay transceiver design.

Abstract-This paper presents an Irregular Distributed SpaceTime (Ir-DST) coding scheme designed for near-capacity cooperative communications where the system's effective throughput is also maximized with the aid of a joint source-and-relay mode design procedure. At the source node, a serial concatenated scheme comprising an IRregular Convolutional Code (IRCC), a recursive Unity-Rate Code (URC) and a Space-Time Block Code (STBC) was designed for the sake of approaching the corresponding source-to-relay link capacity, where the IRCC was optimized with the aid of EXtrinsic Information Transfer (EXIT) charts. At the relay node, another IRCC is concatenated serially with an identical STBC. Before transmitting the relayed information, the relay's IRCC is re-optimized based on EXIT chart analysis for the sake of approaching the relay channel's capacity as well as for maximizing the relay's coding rate, which results in a maximized effective throughput. We will demonstrate that the topology of the Ir-DST system coincides with that of a Distributed Turbo Code (DTC). At the destination node, a novel three-stage iterative decoding scheme is constructed in order to achieve decoding convergence to an infinitesimally low Bit Error Ratio (BER). Finally, our numerical results show the proficiency of our joint source-and-relay mode design procedure, demonstrating that the proposed Ir-DST coding scheme is capable of near-capacity cooperative communications as well as of maximizing the effective throughput.
