In this paper, we introduce the concept of nonsystematic turbo codes and compare them with classical systematic turbo codes. Nonsystematic turbo codes can achieve lower error floors than systematic turbo codes because of their superior effective free distance properties.

In this paper we introduce a new coding scheme - so-called laminated turbo codes. It is characterized by a block-convolutional structure that enables us to combine the advantages of a convolutional encoder memory and a block-oriented decoding method. We show that this block-convolutional structure is superior in terms of its error correction capability

Turbo multiuser detection for turbo-coded CDMA
WCNC. 1999 IEEE Wireless Communications and Networking Conference (Cat. No.99TH8466), 2003An iterative receiver structure is proposed for decoding multiuser information data in a turbo-coded DS-CDMA system. The receiver performs two successive soft-output decisions, achieved by a soft-input soft-output (SISO) multiuser detector and a bank of single-user SISO channel decoders, through an iterative process.

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.

Zwei wichtige Vorbemerkungen: Wahrend die bisherigen Kapitel uneingeschrankt fur alle Rechnersysteme gelten, ist der folgende Text in erster Linie fur solche Leser von Interesse, die eine grafikfahige Version von TURBO erworben haben. — Wir gehen zunachst davon aus, das unser Rechnersystem die unter TURBO vorhandenen standardmasigen Grafikmoglichkeiten

French Turbo–Propeller and Turbo–Reaction Engines
The Journal of the Royal Aeronautical Society, 1949When, in the course of his visit to Paris in May 1948, Dr. Roxbee Cox invited me to lecture to the Royal Aeronautical Society on our work in the field of turbopropeller and turbo-reaction engines, I was torn between two sentiments; the great honour which was done to me, and the seeming temerity for a French engineer to discourse on aircraft turbines ...
