Badlishah, Ahmad, Prof. Dr. Mohd Abdur Rashid, Dr. nasim751@yahoo.com syedalwee@unimap.edu.my hilaladnan@unimap.edu.my badli@unimap.edu.my abdurrashid@unimap.edu.my Modified Double Weight (MDW) code Multiple-access interference (MAI) NAND/AND/complementary detection Optical-code-division-multiple access (OCDMA) Link to publisher's homepage at http://www.elsevier.de/ In this paper, we have extensively analyzed the OCDMA system performance using modified double weight (MDW) code with NAND detection technique as newly developed by the authors. In theoretical analysis, various noises and multiple-access interference (MAI) effect were taken into account. The system performance was characterized by the signal-to-noise ratio (SNR) and the bit-error-rate (BER). The analysis results obtained with NAND detection technique were compared with those as obtained with complementary and AND subtraction techniques. The comparison results revealed that the NAND detection technique with MDW code can support more number of active users and improve the system performance compared to complimentary and AND subtraction techniques. We also ascertained by simulation experiment that the BER performance of the system with NAND detection technique is greatly improved as compared to the complementary and AND subtraction technique. 2014-03-10T08:07:46Z 2014-03-10T08:07:46Z 2013-07 Article Optik, vol. 124(13), 2013, pages 1402-1407 0030-4026 http://www.sciencedirect.com/science/article/pii/S0030402612002392 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32483 en Elsevier GmbH |
