Utilizing an empirical path loss model proposed in the first paper of a two-part series, the bit error rate performance of short-range non-line-of-sight ultraviolet communication receivers is analyzed. Typical photodetector models and modulation formats are considered. The authors' results provide semi-analytical prediction of the achievable communication performance as a function of system and channel parameters, and serve as a basis for system design. UltraViolet (UV) technology is a candidate for Wireless Optical Communications (WOC) due to the unique features of Non-Line-Of-Sight (NLOS) connectivity and range-dependent attenuation.
