| Abstract: | Two-dimensional prime sequence codes for synchronous fiber-optic CDMA (Code di vision multiple acess) network is derived from modified prime sequence codes.The bit error probability performa nce of the proposed system using an avalanche photodiode (APD) is analyzed where the Gaussian approximation of the APD output is employed and the effect of the APD noise,thermal noise,and multiple access interference are considered.Numerica l results reveals that the performance of 2-D FO(Fiber optic)-CDMA system is muc h better than that of 1-D FO-CDMA system and the bandwidth occupied by 2-D FO-CDMA system is relatively small. |

| Keywords: | fiber-optic CDMA prime sequence codes two-dimensional optical orthogonal code |
