Abstract

In ultraviolet communications, the transceiver jitter effects have been ignored in previous studies, something that can result in non-negligible performance degradation especially in vibration states or in mobile scenes. To address this issue, we model the relationship between the received power and transceiver jitter by making use of a moment-based density function approximation method. Based on this relationship, we incorporate the transceiver jitter effects in combination with the Poisson distribution. The error rate results are obtained assuming on–off key modulation with optimal threshold-based detection. We validate the error rate expressions by comparing the analytical results to Monte Carlo simulation results. The results show that the transceiver jitter effects cause performance degradation especially in smaller transceiver elevation angles or shorter range cases, which are often adopted in short-range ultraviolet communications. The results also show that larger elevation angle cases have a better performance with respect to antijitter and may perform better compared to smaller elevation angle situations in the case of a larger standard deviation of jitter. This work studies for the first time the transceiver jitter effects in ultraviolet communications and provides guidelines for experimental system design.
