ABSTRACT
In this study, we investigate the performance of soft and hard decision-making processes in ultraviolet (UV) communication systems. We delve into the intricacies of the guard slot within the pulse position modulation (PPM) technique and assess the efficacy of single reception versus diversity reception on UV signal transmission. Our experimental results delineate the influence of these methodologies on the system’s bit error rate (BER). By refining the signal synchronization and modulation methodologies in the existing UV communication framework, we achieved significant enhancements in transmission distance and BER reduction. Notably, we realized a trans- mission rate of 200 kbps with a BER below 1 × 10^(−6) over 180 m and 100 kbps at a BER under 1% over 240 meters.
