Performance Analysis of Multi-QoS Model of OCDMA System by Adopting OPPM Signalling and Switching
نویسنده
چکیده
In this paper, optical CDMA which combines the large bandwidth of the fibre medium with the flexibility of the CDMA technique to achieve high speed connectivity has been used. For achieving this purpose, OPPM signalling and switching techniques have been employed. This helps in the achievement of high tolerance to Multiple Access Interference, further resulting in improvement of both the Bit Error Rate and optical channel capacity without the need to decrease the light pulse width. An OPPM scheme to support multimedia services with different transmission rates and Quality of Service requirements is proposed. Packet Switching technique has been employed to help in the transfer of data in the form of packets from the source to the destination via a specified route. The results are calculated by using PPM signalling and switching technology.But switching technology has been found to be far better than the OOK-OCDMA if the average power has been considered as the restraining factor.

The idea of using quasi-linear piecewise models has been established on the decomposition of complicated nonlinear systems, simultaneously designing with local controllers. Since the proper performance and the final system close loop stability are vital in multi-model controllers designing, the main problem in multi-model controllers is the number of the local models and their position not payi...

متن کاملMulti-level Thrust Ripples Minimization of Linear Flux Switching Motors With Segmented Secondary by Combined Genetic Algorithm and Response Surface Methodology
Linear flux switching motors with simple passive segmented secondary, referred as Segmented Secondary Linear Flux Switching Motors (SSLFSMs), have low cost secondary and therefore are applicable to transportation systems like Maglev. However, it is shown that the SSLFSMs suffer from high thrust ripples. In this paper, minimizing SSLFSM thrust ripples besides maximizing its developed thrust are ...
