Abstract

Optical camera communication (OCC) leverages camera image sensors for data reception from light sources but faces challenges of low data rates and high bit error rates. This study introduces an OCC system combining orthogonal frequency division multiplexing with a UNet-based equalizer for signal denoising. Using pixel rows as transmission units, the system achieves a data rate of 9.2 kbps and a bit error rate of

8.41 \times 1 0^{- 3}

at 1 m. Python scripts facilitate system control, optimization, and embedded deployment, highlighting OCC’s potential for next-generation communication systems with improved performance over conventional methods.

OCC系统OFDM调制的实时实现：基于unet的信号去噪和误码率优化均衡器

光学相机通信（OCC）利用相机图像传感器接收来自光源的数据，但面临着低数据速率和高误码率的挑战。本文介绍了一种将正交频分复用与基于unet的均衡器相结合的信号去噪OCC系统。以像素行为传输单位，在1m的传输速率为9.2 kbps，误码率为8.41×10−3。Python脚本有助于系统控制、优化和嵌入式部署，突出了OCC在下一代通信系统中的潜力，其性能优于传统方法。
