OCDMA System Performance review- A Review Paper

Computer Science & Engineering

this paper present analysis of various methods for Optical code division multiple access code technique. Codes are designed based on the cross correlation property .The cross correlation may be unit or zero. The MDW, MS and FCC codes, follows the unit cross correlation and MD,MZCC code follows the zero cross correlation. The code also categorized based on unipolar and bipolar code. The analysis is performed for variation in number of users, received power, data bit rate and their effect on bit error rate (BER). The various detection techniques such as subtraction, AND detection and NAND direct detection method are also used for code detection so analysis of given methods are also analysed.
