    Abstract
  • A new class of generalized large area synchronization (LS) codes named daoben lab (DBL) access codes was presented. DBL access codes are generated from the left or right kronecker product of the LS codes and the extending matrix, and are called DBL left-product codes and DBL right-product codes, respectively. Two kinds of DBL access codes have their own features. The DBL right-product codes are divided into several groups such that the larger zero correlation window (ZCW) between two different code groups can be obtained and the number of available codes is increased. In addition, the aperiodic auto-correlation functions (ACF) and cross-correlation functions(CCF) of the codes within one group are determined by the extending matrix. The DBL left-product codes are also divided into several groups and the ZCW between two different code groups is same as that of LS code and the number of available codes is not increased, but the ZCW is equally as length as the former LS code used to do kronecker product with the orthogonal extending matrix within one group. Computer simulation has also validated the features of two kinds of DBL access codes.
