摘要：

In this paper, we address the problem of the algebraic construction of a particular family of optical codes for use in code division multiple access (CDMA) fiber-optic local area networks. The conditions that the code families have to satisfy when used in such systems are reviewed. The newly constructed codes are called quadratic congruence codes, and the construction of the corresponding sequences is based on the number theoretic concept of quadratic congruences. It is shown that p - 1 codes exist for every odd prime p, and can serve as many as p - 1 different users in the fiber-optic code division multiple access system. The newly constructed codes belong to the family of optical orthogonal codes, and we establish their auto- and cross-correlation properties and compare their performance to the previous optical codes. We present examples of the codes and the examples of their auto- and cross-correlation functions.
