An Efficient Hybrid Decoder for Block Turbo Codes [PDF]
In this letter, an efficient hybrid decoder for block turbo codes (BTCs) is proposed to improve the hybrid BTC decoder developed by Al-Dweik et al. A simple formula for estimating the extrinsic information is first derived. Then the proposed decoder is constructed by modifying the decoder of Al-Dweik et al. using the formula.

Low Complexity Syndrome-Based Decoding Algorithm Applied to Block Turbo Codes
This paper presents a technique for reducing the decoding complexity of block turbo code with an extended Hamming code as a component code. In conventional decoding algorithms, when an input vector has a zero syndrome, complexity can be reduced by using ...

Performance comparison of convolutional and block turbo codes
Turbo code is recommended as a channel coding scheme, which has been shown to be capable of performing close to the Shannon Limit. In this paper, we compare the performance of both convolutional and block turbo codes over AWGN and Rayleigh fading channels.

Block turbo codes for space-time systems
Advances in the field of information theory have shown that wireless systems using multiple transmitters and multiple receivers can significantly improve the spectral efficiency. Systems using transmit and receive diversity associated with coding such as space time trellis codes have since been developed.

Irregular Vector Turbo Codes with low complexity
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 ...

Turbo code design for short blocks [PDF]
This work considers the design of short parallel turbo codes (PTCs) with block lengths in the order of (a few) hundred code bits. In particular we aim at designing codes with large minimum distance. To this end a structured approach is presented to find suitable component code configurations, as well as interleavers.
