Iterative (turbo) soft interference cancellation and decoding for coded CDMA

by Xiaodong Wang, H. Vincent Poor - IEEE Trans. Commun , 1999
"... Abstract — The presence of both multiple-access interference (MAI) and intersymbol interference (ISI) constitutes a major impediment to reliable communications in multipath code-division multiple-access (CDMA) channels. In this paper, an iterative receiver structure is proposed for decoding multiuse ..."
Abstract - Cited by 456 (18 self) - Add to MetaCart
iteration, extrinsic information is extracted from detection and decoding stages and is then used as a priori information in the next iteration, just as in Turbo decoding. Given the multipath CDMA channel model, a direct implementation of a sliding-window SISO multiuser detector has a prohibitive

Noncoherent iterative (turbo) decoding

by Giulio Colavolpe, Gianluigi Ferrari, Riccardo Raheli , 2000
"... Recently, noncoherent sequence detection schemes for coded linear and continuous phase modulations have been proposed, which deliver hard decisions by means of a Viterbi algorithm. The current trend in digital transmission systems toward iterative decoding algorithms motivates an extension of these ..."
Abstract - Cited by 18 (3 self) - Add to MetaCart
. Applications to the combined detection and decoding of differential or convolutional codes are considered. Further applications to noncoherent iterative decoding of turbo codes and serially concatenated interleaved codes are also considered. The proposed noncoherent detection schemes exhibit moderate

Linear Iterative Turbo-Equalization (LITE) for Dual Channels

by Andrew Singer, Jill Nelson, Ralf Koetter - in Proc. 33th Asilomar Conf. on Signals, Systems, and Computers , 1999
"... We examine a point-to-point communications scenario in which two or more separate, but known, channels are available for data transmission. While sending the same data across multiple channels provides channel diversity, we introduce additional temporal diversity by permuting the order of the data p ..."
Abstract - Cited by 6 (4 self) - Add to MetaCart
prior to transmission over one or more of the channels. As a receiver, we introduce a low complexity iterative equalization algorithm, inspired by iterative decoders for turbo-codes, which we call linear iterative turboequalization (LITE). The LITE algorithm contains one minimum mean square error linear

Courville, “Geometrical interpretations of iterative ’turbo’ decoding

by B. Muquet, P. Duhamel, M. De Courville - in Proceedings ISIT , 2002
"... Abstract: This paper provides a geometrical interpretation of the decoding of bit-interleaved coded modulation (BICM). Compared to our previous work reported in [9], it provides a complete interpretation of the iterative decoding algorithm and identifies some additive projections that are performed. ..."

A 50 Mbit/s Iterative Turbo-Decoder

by F. Viglione, G. Masera, G. Piccinini, M. Ruo Roch, M. Zamboni - Proc. Design, Automation and Test in Europe Conf. (DATE , 2000
"... Very low bit error rate has become an important constraint in high performance communication systems that operate at very low signal to noise ratios: due to their impressive coding gains, turbo codes have been proposed for several applications, although they suffer a large decoding delay. This paper ..."

An Iterative, Turbo-like Approach to Convolutional Decoding

by Laurent Schmalen, Marc Adrat
"... Abstract. In this paper we present a new method to decode convolutional codes. The method is based on the Turbo principle which was originally proposed to decode parallel concatenated convolutional codes. It becomes possible because of a reinterpretation of the encoder structure. The newly interpret ..."

Iterative Turbo Decoding Using Gibbs Sampling

by Karim Abed-meraim, Vincent Buchoux, Olivier Cappé, Eric Moulines
"... This paper discusses an iterative multiuser receiver for codedivision multiple access (CDMA) with forward error control coding. The receiver is derived from the maximum aposteriori (MAP) criterion for the joint received signal. A major drawback of the MAP receiver is its heavy computational cost tha ..."

2Iterative (Turbo) Joint Rate and Data Detection in Coded CDMA Networks

by Stefano Buzzi, Stefania Sardellitti
"... Summary. A convolutionally coded CDMA data network wherein each user may transmit at one out of a set of possible data rates is considered in this chapter. The problem of joint detection of the data-rate of each user and of the corresponding information symbols is considered. In particular, it is sh ..."
Abstract - Add to MetaCart
, it is shown here that the so-called turbo principle can be used also for joint rate and data detection, and indeed an iterative (turbo) procedure is derived wherein the single-user decoders, and the data-rate detectors for each user exchange information in order to achieve lower and lower detection error
