Komunikasi cahaya boleh dilihat (VLC) dan julat cahaya boleh dilihat ialah teknik yang boleh digunakan untuk sistem pengangkutan pintar (ITS). Mereka menggunakan setiap diod pemancar cahaya (LED) unik di jalan raya untuk penghantaran data dan anggaran jarak. VLC dan julat serentak boleh digunakan untuk meningkatkan prestasi kedua-duanya. Ia adalah perlu untuk mencapai kadar data pantas dan julat ketepatan tinggi apabila menghantar data VLC dan menganggarkan julat secara serentak. Kami menggunakan kaedah modulasi isyarat modulasi lebar nadi (PWM) untuk meningkatkan kadar data. Walau bagaimanapun, apabila menggunakan PWM untuk penghantaran data VLC, imej pemancar LED ditangkap pada tahap pencahayaan yang berbeza dan mudah tepu, dan ketepuan LED membawa kepada anggaran julat yang tidak tepat. Dalam makalah ini, kami mewujudkan komunikasi cahaya nampak serentak dan sistem julat untuk ITS menggunakan PWM. Di sini, kami menganalisis masalah ketepuan LED dan menggunakan interpolasi bikubik untuk menyelesaikan masalah ketepuan LED dan dengan itu, meningkatkan komunikasi dan prestasi julat. Komunikasi dan julat serentak didayakan menggunakan kamera stereo. Komunikasi direalisasikan menggunakan gabungan nisbah maksimum (MRC) manakala julat dicapai menggunakan korelasi fasa sahaja (POC) dan penghampiran fungsi sinc. Tambahan pula, kami mengukur prestasi sistem cadangan kami menggunakan percubaan percubaan lapangan. Keputusan menunjukkan bahawa prestasi bebas ralat boleh dicapai sehingga jarak komunikasi 55 m dan ralat anggaran julat adalah di bawah 0.5m dalam lingkungan 60m.

Abstract: Visible light communication (VLC) and visible light ranging are applicable techniques for intelligent transportation systems (ITS). They use every unique light-emitting diode (LED) on roads for data transmission and range estimation. The simultaneous VLC and ranging can be applied to improve the performance of both. It is necessary to achieve rapid data rate and high-accuracy ranging when transmitting VLC data and estimating the range simultaneously. We use the signal modulation method of pulse-width modulation (PWM) to increase the data rate. However, when using PWM for VLC data transmission, images of the LED transmitters are captured at different luminance levels and are easily saturated, and LED saturation leads to inaccurate range estimation. In this paper, we establish a novel simultaneous visible light communication and ranging system for ITS using PWM. Here, we analyze the LED saturation problems and apply bicubic interpolation to solve the LED saturation problem and thus, improve the communication and ranging performance. Simultaneous communication and ranging are enabled using a stereo camera. Communication is realized using maximal-ratio combining (MRC) while ranging is achieved using phase-only correlation (POC) and sinc function approximation. Furthermore, we measured the performance of our proposed system using a field trial experiment. The results show that error-free performance can be achieved up to a communication distance of 55 m and the range estimation errors are below 0.5m within 60m.
