Optical signal reinstatement (OSR) is a common technique used in high-speed communication systems. OSR can be achieved using various techniques such as; semiconductor optical amplifiers, optical parametric amplifiers, optical loop mirror, and etc. The existing OSR techniques of a maximum speed of 40 Gb/s for long haul communication of 300 km transmission distance offer the 10−10 BER of and noise (phase...
In this paper, studies are performed and techniques are proposed for interference mitigation in Transmitted Reference ultra wideband (TR-UWB) system. The best method for suppressing and reducing the mutual interference is without modifying interfering systems. The coexistence of multisystem is given by: (a) Interference reduction from UWB systems to other narrowband (single and multiple) and wideband...
For high data rate ultra wideband communication system, performance study RAKE-MMSE time domain equalization (both LE and DFE) is attempted in these paper. We focus our attention on the effects of the number of RAKE fingers and equalizer taps on the error performance. The proposed receiver combats inter-symbol interference by taking advantage of the RAKE and equalizer structure. The receiver performance...
