An analog joint source channel coding (JSCC) system is developed for wireless optical
communications. Source symbols are mapped directly onto channel symbols using space …

Channel coding is a fundamental tool to improve performance in most of the digital
transmission systems. By yielding the same performance with a significant saving in the …

Coherent optical communication systems offer improved sensitivity over direct detection
systems. However, device and subsystem imperfections will diminish the sim of the potential …

An analysis of the sensitivity of an optical receiver in a digital communication system using
Manchester (biphase) coding is performed. Both cases of pin and avalanche photodiodes …

In order to mitigate bandwidth attenuation of diffusion link visible light communication
