Performance enhancement of OCDMA system using NAND detection with modified double weight (MDW) code for optical access network
Nasim, Ahmed; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr.; R. Badlishah, Ahmad, Prof. Dr.; Mohd Abdur Rashid, Dr. (Elsevier GmbH, 2013-07)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 ... -
Performance improvement of spectral amplitude coding-optical code division multiple access systems using NAND detection with enhanced double weight code
Nasim, Ahmed; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; R. Badlishah, Ahmad, Assoc. Prof. Dr. (The Optical Society of Japan, 2012-01)The bit-error rate (BER) performance of the spectral amplitude coding-optical code division multiple access (SACOCDMA) system has been investigated by using NAND subtraction detection technique with enhanced double weight ...
