Irregular Vector Turbo Codes with low complexity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2022
The term Block Turbo Code typically refers to the iterative decoding of a serially concatenated two-dimensional systematic block code. This paper introduces a Vector Turbo Code that is irregular but with code rates comparable to those of a Block Turbo ...

Where to go from here? New cross layer techniques for LTE Turbo-Code decoding at high code rates [PDF]

open access: yesAdvances in Radio Science, 2018
The wide range of code rates and code block sizes supported by todays wireless communication standards, together with the requirement for a throughput in the order of Gbps, necessitates sophisticated and highly parallel channel decoder architectures ...

Nested turbo codes for the costa problem [PDF]

open access: yes, 2008
Driven by applications in data-hiding, MIMO broadcast channel coding, precoding for interference cancellation, and transmitter cooperation in wireless networks, Costa coding has lately become a very active research area.

Turbo codes and turbo algorithms

open access: yesJournal of Communications Software and Systems, 2017
In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular trellis termination of recursive systematic convolutional codes and double-binary turbo codes associated

Exit chart analysis of parallel data convolutional codes [PDF]

open access: yes, 2005
We recently proposed a new class of turbo-like codes called parallel data convolutional codes (PDCCs). The distinct characteristics of PDCCs include parallel data input bits and a self-iterative soft-in/soft-out a posteriori probability(APP) decoder. In

Turbo Equalization With Irregular Turbo Codes [PDF]

open access: yes2007 4th International Symposium on Wireless Communication Systems, 2007
We analyze a turbo equalization system that combines maximum a posteriori probability (MAP) equalization with irregular turbo codes. Our goal is to approach the information capacity limit for severe inter-symbol interference (ISI) channels. To this end, we optimize the degree profile of irregular turbo codes by maximizing the minimum distance between ...

Shaping EXIT Functions of Turbo Codes [PDF]

open access: yes, 2008
This paper investigates the shaping of the extrinsic information transfer (EXIT) functions of parallel turbo codes, when the turbo code is used as an outer code in a serially concatenated scheme.

Frequency Domain Hybrid-ARQ Chase Combining for Broadband MIMO CDMA Systems [PDF]

open access: yes, 2009
In this paper, we consider high-speed wireless packet access using code division multiple access (CDMA) and multiple-input multiple-output (MIMO). Current wireless standards, such as high speed packet access (HSPA), have adopted multi-code transmission ...
