Abstract: Today digital communications is at an advanced level. Performance of digital communication system is also play critical Performance optimization of digital communications systems can be done by fine-tuning of parameters of modern digital communications systems. The accurate knowledge of the parameters characterizing the quality of a communication channel is extremely important for efficient data transmission. The application of the Particle Swarm Optimization (PSO) algorithm successfully applied to wide range of engineering problems. In very recent this algorithm becomes very popular due to its simplicity and effectiveness. Researchers have explored PSO algorithm for communication engineering applications. This algorithm can be successfully applied to various digital communication systems for improving performance. The purpose of this paper to explore the different applications of PSO in digital communication system.
Keywords: Digital communication system; Particle swarm optimization.
