Abstract: In this paper, we propose the construction of two code generators for optical ZCZ codes of Zcz = 4n􀀀2 with positive n and Zcz = 1 using the Sylvester-type Hadamard matrix, which are called ROM-type and non ROM-type code generators. The optical ZCZ code is a set of pairs of binary and bi-phase sequences with zero correlation zone. An optical code division multiple access (CDMA) system using optical ZCZ code can remove co-channel interference and influence of multi-path. This ROM-type code generator can be constructed by a ROM and an up-counter. Similarly, the non ROM-type code generator can be constructed by an up-counter and logic gates. The ROM-type and non ROM-type code generators are implemented on a field programmable gate array (FPGA) corresponding to 600; 000 logic gates, and the non ROM-type code generator can reduce logic elements and memory bits than the ROM-type code generator, and can operate faster than the ROM-type code generator.
