Error Rate Analysis of 32-FSK Modulation in Wireless Fading Channels using MATLAB: Impact of Delay Vector and K-Factor

This paper investigates the error rate performance of wireless communication systems employing 32-Frequency Shift Keying (32-FSK) modulation in fading environments, using MATLAB as the simulation platform. Key parameters such as delay vector, Doppler shift, K-factor, and diffuse Doppler shift are systematically varied to analyze their effects on system performance. Results demonstrate that error rates increase with larger delay vectors but are significantly mitigated by higher K-factor values, reflecting the influence of a stronger Line-of-Sight (LOS) component. The study underscores the effectiveness of 32-FSK modulation in achieving low error rates under optimized conditions and provides MATLAB-based insights for designing robust communication systems in multipath fading scenarios.
