New approach of Double Weight Code Family Detection using reduced set of Fiber Bragg Gratings
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
To increase the number of users in the double weight (DW) code family, a mapping technique is applied. This mapping technique increases the number of users but at a cost of unfixed cross-correlation property. The complementary ...
