摘要：

In this paper, we propose the construction of two code generators for an optical ZCZ code of length N = 2(n), family size M = N/2-2 and zero correlation zone 1, 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 this 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, this 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 400,000 logic gates, and the non ROM-type code generator can reduce logic elements than the ROM-type code generator.
