Near-Capacity Iteratively Decoded Binary Self-Concatenated Code Design Using EXIT Charts

In this paper, Extrinsic Information Transfer (EXIT) charts are used to design binary SElf-Concatenated Convolutional Codes employing Iterative Decoding (SECCC-ID) for communicating over both uncorrelated Rayleigh fading and Additive White Gaussian Noise (AWGN) channels. Recursive Systematic Convolutional (RSC) codes are selected as constituent codes, an inter-leaver is used for randomising the extrinsic information exchange of the constituent codes, while a puncturer assists them in increasing the achievable bandwidth efficiency. At the receiver, self-iterative decoding is invoked for exchanging extrinsic information between the hypothetical decoder components.
