SAC OCDMA systems are limited byphase induced intensity noise (PIIN), which is a signal dependent source of noise. Our proposed techniquereduces the PIIN by dividing the spectrum of the signal into two or more, and detecting each spectrumby a different photodiode. The DSBD scheme reduces the detected optical power at photodetection, thusresulting in a higher mitigation of the PIIN. Theoretical results show that DSBD demonstrate noticeableimprovement over traditional balanced detection technique, for example an up to 33% increase in thenumber of active users can be achieved, and at least 1 × 10-3b/s Hz increase in the spectral efficiency isobtained. However, the SDBD is more complex and append more constrains on system components 2014-03-12T04:48:45Z 2014-03-12T04:48:45Z 2013-12 Article Optik, vol. 124(23), 2013, pages 5994-5999 0030-4026 http://www.sciencedirect.com/science/article/pii/S0030402613006645 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32615 en Elsevier GmbH |
