A study of visible light communication channels for high speed roadways
MetadataShow full item record
A visible light communication channel study is conducted for high speed roadways under clear night sky conditions in which street light poles transmit to receivers on top of moving vehicles. A detailed analysis of the communication channel is undertaken. Exact and approximate analytical DC channel responses are obtained and analyzed, and the channel capacity and RMS time delay spreads are derived. Numerical studies verify that visible light communications are feasible for high speed roadways.
