Performance analysis of V2V visible light communication systems under diverse scenarios

Abstract The present paper analyzes the performance of vehicle-to-vehicle (V2V) visible light communication (VLC) systems across various practical scenarios. Metrics including bit error rate (BER), frequency response, signal-to-noise ratio (SNR), channel capacity, and time delay are analyzed for three distinct scenarios. Results indicate that inadequate lateral displacement between vehicles of adjacent lanes can significantly impact BER performance. Moreover, frequency response analysis reveals undesirable periodic variations in scenario-2, posing challenges for V2V communication. In the case of non-line-of-sight (NLoS) communication (scenario-3), both longitudinal and lateral displacements exhibit notable impacts across all analyzed metrics.
