The novel generator/correlator is constructed from an efficient generator/correlator for two uncorrelated Golay pairs of length 2N {\textperiodcentered} 10M {\textperiodcentered} 26P . The proposed architecture permits to transmit both pairs in a quadrature modulation scheme (QAM or QPSK). The reduced number of operations needed in comparison with a straightforward correlator and the large Zero Correlation Zone (ZCZ) makes these sequences good candidates to be used in QS-CDMA (Quasi-Synchronous CDMA).}, keywords = {Efficient correlator, Golay pairs, GPC, QSCDMA., ZCZ}, issn = {1089-7798}, doi = {10.1109/LCOMM.2012.091712.121240}, author = {Garc{\'\i}a, Enrique and Ure{\~n}a, J. and J.J.
