NGUYEN et al. give a method for constructing binary CP constant-weight (CPC) codes,then they construct protocol sequences with good performance by using the codes. To makethe minimum distance of the CP codes large enough, Nguyen et al. select two classes of maxi-mum distance separable(MDS) codes which are q-ary Reed-Solomon (R-S) codes and q-arygeneralized Berlekamp-Justesen(B-J) codes. The generalized B-J codes are more 展开更多

1 Preliminaries The mathematical definition of the two-dimensional optical orthogonal code(2-D OOC)is as follows: Definition 1. A(mn, ω,λ_a,λ_c) 2-DOOC consists of a set of(O, 1) m×n matri-
