Random coding applied to blocks of size k offers minimum distances as large as k/4 roughly, but is not decodable in practice. We propose a decodable multidimensional extension of classical two-dimensional turbo codes, giving minimum distances comparable to those of random codes.

Proceedings of MILCOM '95, 2002
We introduce multiple turbo codes and a suitable decoder structure derived from an approximation to the maximum a posteriori probability (MAP) decision rule, which is substantially different from the decoder for two-code-based encoders. We developed new rate 1/3 and 2/3 constituent codes to be used in the turbo encoder structure.

Turbo-Like Codes Constructions
2014This chapter provides design, analysis, construction, and performance of the turbo codes, serially concatenated codes, and turbo-like codes including the design of interleavers in concatenation of codes. Also this chapter describes the iterative decoding algorithms for these codes.

2000 IEEE International Symposium on Information Theory (Cat. No.00CH37060), 2002
This paper describes a new class of codes, chaotic turbo codes. They were born from a symbiosis between a chaotic digital encoder and a turbo code. This paper investigates the most important properties of both chaotic digital encoders and turbo encoders in order to understand how the two complement each other.

The multifold turbo coding, designed to provide multiple extrinsic estimates and LLRs on a bit basis during decoding iterations, is introduced. Component encoders accept various combinations of information segments, which are obtained by equally dividing the information block prior to encoding.

This paper examines the performance of turbo-codes with non-identical component codes. We show that asymmetric turbo-codes provide good performance with respect to both the "error-floor" and the "pre-error-floor" regions of the bit error rate curve.

Turbo Codes and Turbo Equalization
2000Turbo codes, introduced by Berrou, et al.[Berrou et al., 1993] in 1993, provide large coding gain for the memoryless additive white Gaussian noise (AWGN) channel and bring the system performance to within 1 dB from the Shannon capacity limit [Shannon, 1948]. The superior performance soon caused turbo codes to receive intense study.

IEEE Transactions on Communications, 2001
Summary: This letter is concerned with a family of modified turbo-type codes, referred to as turbo-SPC (single parity check) codes. A technique based on the SPC code is introduced to replace puncturing for rate adjustment. A noticeable feature of the proposed scheme is the significantly reduced decoding complexity compared with the standard punctured ...

In this paper we investigate turbo coding for BLAST (Bell Labs layered space-time) by encoding single user data streams and transmitting the symbols in different antennas. At the receiver we adopt an MMSE nulling, incremental decoding and soft cancellation approach to decode the symbols.

This book is devoted to one of the essential functions of modern telecommunications systems: channel coding or error correction coding. Its main topic is iteratively decoded algebraic codes, convolutional codes and concatenated codes. It also presents digital modulation with which channel coding is closely associated to make up the heart of the ...
