Abstract
2n modified prime codes are designed for all-optical code-division multiple access (CDMA) networks using very simple encoders and decoders. The proposed code is obtained from an original 2n prime code of prime number P. By padding P-1 zeros in each `subsequence´ of codewords in the corresponding 2n prime code. The cross-correlation constraint of the resulting 2n modified prime code is equal to one, as opposed to two for a 2n prime code. For a given bit error rate (BER), the proposed code can thus be used to support a larger number of active users in the fibre optic CDMA network than a 2n prime code. Moreover, using the former can also reduce code length and weight compared with employing the latter to achieve the same BER
