  Implementation of FSO Link for Full Duplex Short Range Communication

  By Prof. Dhaval Shah, Dilip Kumar Kothari

  Abstract: Extensive data transfer is a need of all modern communicating devices. Wired communication requires lots of bulky wires to be laid everywhere. To setup a small ad hoc network, it is not advisable to lay down long wires. Other than requirement of wires, one also needs very good communication speed to withstand the need of very high bandwidth for multimedia data transfer. A communication link that satisfies both the requirements …

  BER Performance of Lognormal Channel Model with Imperfect CSI for Free Space Optical Communication

  By Prof. Dhaval Shah, Dr. Dilip Kothari

  Abstract: ABSTRACT In this paper, Lognormal Channel model has discussed with the assumption of imperfect CSI. This channel model is used to describe atmospheric channel condition in mathematical form. BER performance of this channel model is shown according to turbulence scenario based on BER equation available. Here Gauss-Markov model is used for the case of imperfect CSI. Keywords-lognormal, Imperfect CSI, Gauss-Markov model, scintillation index,turbulence
