@article {8699110620120101, title = {Efficient Dual Domain Decoding of Linear Block Codes Using Genetic Algorithms.}, journal = {Journal of Electrical \& Computer Engineering}, year = {2012}, pages = {1 - 12}, abstract = {A computationally efficient algorithm for decoding block codes is developed using a genetic algorithm (GA). The proposed algorithm uses the dual code in contrast to the existing genetic decoders in the literature that use the code itself. Hence, this new approach reduces the complexity of decoding the codes of high rates. We simulated our algorithm in various transmission channels. The performance of this algorithm is investigated and compared with competitor decoding algorithms including Maini and Shakeel ones. The results show that the proposed algorithm gives large gains over the Chase-2 decoding algorithm and reach the performance of the OSD-3 for some quadratic residue (QR) codes. Further, we define a new crossover operator that exploits the domain specific information and compare it with uniform and two point crossover. The complexity of this algorithm is also discussed and compared to other algorithms [ABSTRACT FROM AUTHOR]}, keywords = {Coding theory, Computational complexity, Data transmission systems, Decoders (Electronics) {\textendash} Software, Genetic algorithms, Performance evaluation}, issn = {20900147}, url = {http://search.ebscohost.com/login.aspx?direct=true\&db=iih\&AN=86991106\&site=ehost-live}, author = {Azouaoui, Ahmed and Belkasmi, Mostafa and Farchane, Abderrazak} } @conference { ISI:000259601400047, title = {Iterative decoding of parallel concatenated block codes}, booktitle = {2008 INTERNATIONAL CONFERENCE ON COMPUTER AND COMMUNICATION ENGINEERING, VOLS 1-3}, year = {2008}, note = {International Conference on Computer and Communication Engineering, Kuala Lumpur, MALAYSIA, MAY 13-15, 2008}, pages = {230-235}, publisher = {Int Islam Univ Malaysia, Fac Engn}, organization = {Int Islam Univ Malaysia, Fac Engn}, abstract = {Parallel concatenated block (PCB) codes based on two systematic block codes and an interleaver are considered. In this study BCH codes are used as component codes. At the reception an iterative decoder using Chase-Pyndiah as Soft-in Soft-Out algorithm is designed. The effects of various component codes, interleaver size and pattern, and the number of iterations are investigated using simulations. The simulation results show that the slope of curves and coding gain are improved by increasing the number of iterations and/or the interleaver size. From the simulations we observe that the codes PCB based on BCH(127,106,7) and BCH(255,215,11) codes are respectively 1.7dB and 2.1 dB from Shannon limit.}, isbn = {978-1-4244-2357-6}, doi = {10.1109/ICCCE.2008.4580602}, author = {Belkasmi, Mostafa and Farchane, Abderrazak} }
