초록

In code division multiple access systems using all-optical signal processing, the optical multiple access interference by simultaneous multiple users degrades the system performance and eventually can limit the number of active users. To reduce the effect of the interference, error-correction codes are used in 2-dimensional FO-CDMA systems. In this paper we propose a method of applying product code to 2-dimensional FO-CDMA systems. The proposed coding scheme can correct a random error and burst errors with small redundancy to the conventional case. In result we show significant performance enhancement of the system in terms of HER, the number of active users.
