Abstract

A variable gain amplifier can be used to reduce the dynamic range of the received signal in an underwater optical wireless communication system.Two methods based on digital to analog converter and digital potentiometer,were discussed in detail.Both the methods can be used to control the amplification gain.Simulation was carried out for the method based on digital potentiometer.The results show that the signal dynamic range is effectively compressed and tends to be stable.
