Title A note on an application of space Time Block Coded DCO-OFDM to Vehicle to Infrastructure Visible Light Communication
Authority Symposium on Information Theory and Its Applications (SITA), pp.555-560
Summary This paper focuses on vehicle to infrastructure visible lightcommunication (V2I-VLC) using two LED headlights as transmitters and photodiodes (PDs) with an optical lens as receiver.We adopt DC-biased optical orthgonal frequency division multiplexing (DCO-OFDM) to realize high data rata V2I-VLC. In V2I-VLC,it is possible to remove background light noise sources by narrowing the receiver's field of view (FOV) by using an optical lens.However,small FOV causes received signal intensity fluctuations ,especially in a driving situation ,and performance may be degraded.To overcome the problem,we adopt a Alamouti-type Space Time Block Coding (STBC) . In this paper, we experimentally demonstrate a 2×1 STBC performance and compare it with the conventional system which the same signals simultaneously transmitted from two headlights. Experimental results show that STBC can't improve bit-error-rate performance because two signals transmitted from each headlights have high space correlation.
