A method for enhancing communication quality in VLC systems based on an improved PSO algorithm
FAN Jun
Abstract：Existing Visible Light Communication(VLC)systems suffer from degraded communication quality due to factors such as light source flicker,multipath effects,and background optical noise.To address this issue,we propose a hybrid approach combining an enhanced Particle Swarm Optimization(PSO)algorithm with simulation modeling to optimize indoor light source layouts.Furthermore,the Constant Modulus Algorithm(CMA)integrated with PSO is applied for blind equalization processing in the communication system.Experimental results demonstrate that the proposed method achieves higher data transmission rates and improved signal throughput while reducing bit error rates,thereby significantly enhancing overall communication quality.
