Performance of Turbo Interference Cancellation Receivers in Space-Time Block Coded DS-CDMA Systems [PDF]
EURASIP Journal on Wireless Communications and Networking, 2008 We investigate the performance of turbo interference cancellation receivers in the space time block coded (STBC) direct-sequence code division multiple access (DS-CDMA) system.

Coding theorems for turbo code ensembles [PDF]
IEEE Transactions on Information Theory, 2002 This paper is devoted to a Shannon-theoretic study of turbo codes. We prove that ensembles of parallel and serial turbo codes are "good" in the following sense.

Stochastic Decoding of Turbo Codes [PDF]
IEEE Transactions on Signal Processing, 2010 Stochastic computation is a technique in which operations on probabilities are performed on random bit streams. Stochastic decoding of forward error-correction (FEC) codes is inspired by this technique. This paper extends the application of the stochastic decoding approach to the families of convolutional codes and turbo codes.

Separate Turbo Code and Single Turbo Code Adaptive OFDM Transmissions
EURASIP Journal on Wireless Communications and Networking, 2009 This paper discusses the application of adaptive modulation and adaptive rate turbo coding to orthogonal frequency-division multiplexing (OFDM), to increase throughput on the time and frequency selective channel.

Spatially Coupled Turbo Codes [PDF]
2014 8th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2014 In this paper, we introduce the concept of spatially coupled turbo codes (SC-TCs), as the turbo codes counterpart of spatially coupled low-density parity-check codes. We describe spatial coupling for both Berrou et al. and Benedetto et al.

CRGAN-based turbo code interleaver for underwater acoustic communications
ICT ExpressThis paper proposes a channel response generative adversarial network (CRGAN)-based turbo code interleaver that estimates a channel response and interleaver indices at a transmitter by using a sound speed profile (SSP) and the ocean environments without ...

The Effect Of Constraint Length And Interleaver On The Performance Of Turbo Code [PDF]
Engineering and Technology Journal, 2010 This paper presents a class derived from convolutional code called turbo code. Theperformance of turbo code is investigated through examining the effect of different constraintlength, the effect of changing rate, and the effect of interleaver on the ...

Quantum Serial Turbo Codes [PDF]
IEEE Transactions on Information Theory, 2008 We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding ...
