Performance comparison of convolutional and block turbo codes
IEICE Electronics Express, 2006 Turbo code is recommended as a channel coding scheme, which has been shown to be capable of performing close to the Shannon Limit. In this paper, we compare the performance of both convolutional and block turbo codes over AWGN and Rayleigh fading channels.

Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
IEEE Transactions on Wireless Communications, 2002 Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of R/spl les/ 1/2. We comparatively studied the performance of a range of binary phase-shift keying turbo equalizers employing block-turbo codes, namely Bose-Chaudhuri ...

Turbo code design for short blocks [PDF]
2016 8th Advanced Satellite Multimedia Systems Conference and the 14th Signal Processing for Space Communications Workshop (ASMS/SPSC), 2016 This work considers the design of short parallel turbo codes (PTCs) with block lengths in the order of (a few) hundred code bits. In particular we aim at designing codes with large minimum distance. To this end a structured approach is presented to find suitable component code configurations, as well as interleavers.

Block turbo codes: towards implementation [PDF]
ICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2002 This paper presents two implementations of the same block turbo decoding algorithm: on the one hand an elementary decoder in association with a sequencer performs the complete turbo decoding process, and on the other hand, the circuit contains one elementary decoder per half-iteration.

Irregular Vector Turbo Codes with low complexity
EURASIP Journal on Wireless Communications and Networking, 2022 The term Block Turbo Code typically refers to the iterative decoding of a serially concatenated two-dimensional systematic block code. This paper introduces a Vector Turbo Code that is irregular but with code rates comparable to those of a Block Turbo ...

Codebook Design for PD-SCMA NOMA Systems
IEEE Access, 2023 The hybrid power domain sparse code non-orthogonal multiple access (PD-SCMA) scheme multiplexes multiple users on a single resource element (RE) both in power and code domains, thus achieving a superior spectral efficiency.
