New Space/Wavelength/Time optical codes for OCDMA
نویسنده
چکیده
New constructions of 3-dimensional optical orthogonal codes are presented. In each case the codes have ideal autocorrelation λa = 0, and cross correlation of λc = 1. All codes produced are demonstrated to be optimal. The constructions utilize a particular automorphism (a Singer cycle) of PG(k,q), the finite projective geometry of dimension k over the field of order q, or its affine analogue in AG(k, q). Key–Words: 3-D code, 3-D OOC, Optical Orthogonal Codes, Johnson bound, finite projective geometries, PG(k,q), Singer cycle. optimal codes

Design and performance analysis of code families for multi-dimensional optical CDMA
A code design algorithm for application in Multi-Dimensional Optical Code Division Multiple Access (MD-OCDMA) for asynchronous optical fibre communication is proposed. Two-dimensional (2-D) wavelength-time or space-time OCDMA and three-dimensional (3-D) space-wavelength-time OCDMA are subsets of MD-OCDMA. Some applications and the performance analysis of the algorithm in 2-D multipulse per row ...
متن کاملA Design of a Wavelength-hopping Time-spreading Incoherent Optical Code Division Multiple Access System
We present the architecture and code design for a highly scalable, 2.5 Gb/s per user optical code division multiple access (OCDMA) system. The system is scalable to 100 potential and more than 10 simultaneous users, each with a bit error rate (BER) of less than 10. The system architecture uses a fast wavelength-hopping, time-spreading codes. Unlike frequency and phase sensitive coherent OCDMA s...
متن کاملAnalysis of MAC Protocols with Correlation Receiver for OCDMA Networks - Part II
In this paper optical code-division multiple-access (OCDMA) packet network is considered, which offers inherent security in the access networks. Two types of random access protocols are proposed for packet transmission. In protocol 1, all distinct codes and in protocol 2, distinct codes as well as shifted versions of all these codes are used. O-CDMA network performance using optical orthogonal ...

3-D W/T/P encoded signal transmitted over free space optical link under the effects of atmospheric turbulences i.e. haze, fog and clear weather. System performance is best when clear weather attenuation is considered (0.1dB/Km) and results degrades in case of Haze (4dB/Km) and worst in Fog (20dB/Km).This system analyzed at varied distance for all the three turbulences, also effect of amplifiers...
متن کاملPerformance Analysis of OCDMA System using W/T Codes
In 1-D optical orthogonal codes, the ratio of code length to the code weight grows rapidly as the number of users increase. If we consider two-dimensional optical orthogonal code then it reduces the length of the code as a result of which BER performance of the system improves. In this paper we have discussed the performance analysis of an incoherent optical code division multiple access scheme...
