Abstrak – The effect of dispersion of fiber on the performance of OCDMA system and to find the limitations imposed by dispersion on number of user and length of transmission. It has been observed that in the bit error rate performance curve the error is decreased when the number of subscriber is increased side by side the optical power is reduced when the users is added. This paper has presente...

This paper develops a performance model of an optically interconnected parallel computer system operating in a distributed shared memory environment. The performance model is developed to reflect the impact of low level optical media access protocol and optical device switching latency on high level system performance. This enables the model to predict the performance impact in supporting distr...

This paper describes mobile backhaul optical access network designs for future cellular systems, in particular, for those systems that exploit coordinated multipoints (CoMP) transmission/reception techniques. Wavelength-division-multiplexing passive optical networks (WDM-PON) are primarily considered and two proposals to enhance mobile backhaul capability of WDM-PONs for CoMP are presented. One...

The OR channel provides an unusual opportunity where single-user decoding permits operation at about 70% of the full multiple-access channel sum capacity. The interleaverdivision multiple access technique applied in this paper can approach that performance with turbo and LDPC solutions. The current paper focuses on very low latency codes with simple Viterbi decoding, intended for very high spee...

Abstract This paper presents the comparison between single channel and multi-channel Medium Access Control (MAC) protocols for broadband optical Local Area Networks. The multi-channel protocol exploits the Wavelength Division Multiplexing (WDM) techniques (each channel corresponds to a different optical wavelength allocated dynamically) and it is based on the Ethernet standard, using a Carrier ...
