| Summary |
A propeller LED transmitter(P-Tx) further boosts image sensor communication (ISC) throughput by mounting LEDs on a rotating arm and encoding data via their On/Off state. Reducing the angular interval per bit increases data rate but also raises the risk of overlapping “light trails” and ensuing interference. To date, no analytical model has linked the control angle to inter-trail interference in P-Tx-based ISC. This paper proposes a fundamental model of light trail generation and blinking control conditions to prevent interference between adjacent light trails. In the proposed model, the luminous energy distribution on the image plane is calculated based on the LED rotation trajectory. We also provide preliminary experimental results to validate the proposed model. |
