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.

EXIT-Chart Aided Design of Irregular Multiple-Rate Quantum Turbo Block Codes
IEEE Access, 2023 We propose a novel quantum turbo short-block code, which subsumes multiple-rate quantum short-block codes (MR-QSBCs) as the outer codes and a quantum unity-rate code (QURC) as the inner code. The proposed design is denoted as MR-QSBC-QURC.

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 ...

New High Performance Deterministic Interleavers for Turbo Codes
Advances in Electrical and Computer Engineering, 2010 Turbo codes offer extraordinary performance, especially at low signal to noise ratios, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing

Concatenated space-time block codes and TCM, turbo TCM, convolutional as well as turbo codes [PDF]
Globecom '00 - IEEE. Global Telecommunications Conference. Conference Record (Cat. No.00CH37137), 2002 Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. We concatenate space-time codes with convolutional codes (CC), turbo convolutional codes (TC), turbo BCH codes (TBCH), trellis coded modulation (TCM) and turbo trellis coded modulation (TTCM) schemes for achieving a high ...
