Optical code division multiple access multiple (OCDMA) is considered as the strongest candidates for the future ultra-high speed optical networks due to the huge bandwidth offered by the system. However, multiple access interference (MAI) which is originated from other simultaneous users is the major reason for the system degradation in the OCDMA systems.… (More)
Optical parallel interference cancellation (OPIC) is effective technique to reduce the multiple access interference (MAI) in the optical code division multiple access (OCDMA). However, the increasing demands for hardware in the OPIC system results into more complexity, higher processing time and cost. In this paper a new receiver is presented which is based… (More)
Although serologic evidence suggests the presence of Q fever in humans and animals in Saudi Arabia and the United Arab Emirates, acute Q fever has not been reported on the Arabian Peninsula. We report the first two cases of acute Q fever in Oman.
