A New Family of 3-d Optical Orthogonal Codes for Optical Cdma Systems with Differential Detection
نویسندگان
چکیده
In this paper, we present a new family of 3-D single pulse per plane codes for differential detection (SPDD) for optical cdma systems (based on the 1-D golomb ruler sequences), which achieve good code cardinality and a very high BER performance. The improved BER performance is obtained by using two codes to encode ‘1’ and ‘0’ bits in the encoder and adopting the Differential Detection in the receiver. The comparison of our 3-D single pulse per plane codes for differential detection with some of the best reported 2-D/3-D codes, shows that the 3-D SPDD codes perform significantly better than the others. The number of simultaneous users supported at 1e-9 is much more increased over those supported by the earlier proposed 2-D/3-D orthogonal codes.

In this paper two families of optical orthogonal codes (OOCs) are algebraically designed by using the Galois field. The first family of codes has nonideal auto and crosscorrelation properties. The second family of codes has ideal auto and cross-correlation properties. It is shown that the codes exist for every prime 2 , 1 c a 1 , 1 c a 1 p p forming a family of OOCs. These codes may serve as ma...
متن کاملModified prime-hop codes for optical CDMA systems - Communications, IEE Proceedings-
In the early stage of optical CDMA systems, the spreading codes, such as optical orthogonal codes (OOCs) and prime codes, are only coded in the time domain. However, the small code size becomes the major issue for one-dimensional codes. To deal with this limitation of onedimensional codes, a new family of two-dimensional codes is proposed for optical CDMA systems. The new codes are modified fro...

In this paper, a new spreading technique for intensity modulation direct detection fiber-optic code-division multiple-access (FO-CDMA) communication systems is proposed. This new spreading technique is based on generalized optical orthogonal codes (OOC) with large cardinality and minimal degradation in performance when compared with a more optimum system, namely, an optical CDMA system using OO...
