Call for Papers: Optical Code Division Multiple AccessGuest Editors Alan Willner, University of Southern California Janet Jackel, Telcordia
Submission Deadline: 1 November 2006Optical code division multiple access (OCDMA) is a technique in which each network user is assigned a unique code rather than a specific wavelength or time slot. This approach allows the same available bandwidth to be shared among the various users, and the code assignments can be flexibly and dynamically changed. CDMA is, of course, quite valuable in wireless systems and had been explored in the optical domain since the mid 1980s. Recently, OCDMA has received increased attention because of significant advances in the enabling technologies, optimal coding schemes, and efficient network algorithms. Due to the increase in interest and the number of published articles in OCDMA, it was felt that the time was ripe for a special issue in the Journal of Optical Networking (JON) on the topic. The research community has demonstrated advances in synchronous and asynchronous systems, based variously on manipulation of phase, frequency, time, and wavelength. A critical question remains as to the ultimate utility of OCDMA, as opposed to or in addition to time and wavelength multiplexing approaches. Applications have been proposed, ranging from PONs for FTTX to the use of codes for flexible networking and for augmented security. This special issue focuses on the technology of OCDMA and on its applications, including its use in networks, possible coexistence with other types of communications, and issues relating to the control and management of networks that incorporate OCDMA. Scope of Submission We welcome submissions on topics including, but not limited to: Novel coding concepts, algorithms, and constructions Synchronous and asynchronous implementations OCDMA-enabled network architectures, topologies, and protocols Enabling hardware Demonstrations of OCDMA Analysis of system performance enhancements Applications of OCDMA and its core technologies Key issues affecting use of OCDMA for privacy and security Comparison and coexistence of OCDMA with other multiuser schemesManuscript Submission To submit to this special issue, follow the normal procedure for submission to JON, indicating ``OCDMA' in the ``Comments' field of the online submission form. For all other questions relating to this feature issue, please send an e-mail to firstname.lastname@example.org, subject line ``OCDMA.'
