  • TITLE: Enhancement in Channel Equalization Using Particle Swarm Optimization Techniques

    AUTHORS: D. C. Diana, S. P. Joy Vasantha Rani

    KEYWORDS: Adaptive Channel Equalization, Decision Feedback Equalizer, Inertia Weight, Mean Square Error, Particle Swarm Optimization

    ABSTRACT: This work proposes an improved inertia weight update method and position update method in Particle Swarm Optimization (PSO) to enhance the convergence and mean square error of channel equalizer. The search abilities of PSO are managed by the key parameter Inertia Weight (IW). A higher value leads to global search whereas a smaller value shifts the search to local which makes convergence faster. Different approaches are reported in literature to improve PSO by modifying inertia weight. This work investigates the performance of the existing PSO variants related to time varying inertia weight methods and proposes new strategies to improve the convergence and mean square error of channel equalizer. Also the position update method in PSO is modified to achieve better convergence in channel equalization. The simulation presents the enhanced performance of the proposed techniques in transversal and decision feedback models. The simulation results also analyze the superiority in linear and nonlinear channel conditions.
