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.

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.

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 ...
