In this thesis, the same architecture is set up to investigate the reduction of multiple-access interference caused by the overlapping wavelength from undesired users. Furthermore, the reduction of optical beat interference (OBI) induced by those adjacent grating chips is examined. The reduction of multiple access interference (MAI) and OBI induced by those adjacent grating chips. FBG written as M-sequence and Walsh codes is proposed for such MAI and OBI cancellation in spectrally balanced photo-detectors. Theoretically, M-sequence and Walsh codes are characterized by nearly the same number of \"on\" chips (i.e., logic \"1\" chips) and \"off\" chips (i.e., logic \"0\" chips). It is seen that the differential decoding scheme characterizes a better performance on eliminating the MAI and OBI problem by mutual cancellation in reflected and transmitted branches of wavelength chips. Furthermore, we propose that the wavelength interleaving allocation method can result in a guard band to suppress OBI. It is shown that SIR has 13 dB improvement with the proposed scheme.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.

Sfar","doi":"10.1109/AINA.2003.1192840","DOIUrl":"https://doi.org/10.1109/AINA.2003.1192840","url":null,"abstract":"The UMTS is setting forth new challenges in terms of integration of end-to-end QoS management. Our approach consists of providing an end-to-end adaptation frame to UMTS commercial services. A commercial service provided to the user should be adapted when selected as well as during its transfer through the different parts of the network. These adaptations are due to the fluctuation of the parameters of the network and the need to adapt the QoS parameters. We then improve QoS management in respect with the contractual commitments, decrease dropped calls rate and optimize resources use by avoiding call rejections and application flow blocking. The four steps of adaptation of our model are guaranteed by an \"adaptation bearer service (ABS)\" which provides technologies to adapt the media to available resources according to the adaptation mode and the localization of resource limitation. At connection time, the service provider or ASP may ask the ABS to adapt the requested service according to the user contract, profile and preferences. At the border of the DiffServ network, the router asks for ABS to adapt the waiting flow of the commercial service according to network resource availabilities and the same at the border of radio network and finally to the terminal according to available CPU, memory, etc. Our approach is intended to take into account the requirements of mastering the degradation of multimedia services to avoid bad renderings and process a degradation as early as possible. In this paper, we will develop our model, the intended extension and our preliminary ongoing developments. In another respect, those control points constitute a cornerstone to set up the verification of fundamental properties such as synchronisation.","PeriodicalId":382765,"journal":{"name":"17th International Conference on Advanced Information Networking and Applications, 2003.
