## 1 Introduction  
The exponential proliferation of wireless devices relying on radio frequency (RF) signals for communication, coupled with the increase in demanding fast data rate applications, has resulted in the saturation of the shared spectrum and bandwidth scarcity. In response to these issues, the use of higher frequency bands, including millimeter waves and terahertz, has emerged as a complementary solution. The current 5G definition considers the use of higher frequency bands around 24.1-27.8 GHz, and it is planned to also utilize the 40 GHz and 60 GHz frequencies in the near future [1, 2]. Above the terahertz spectrum, optical wireless communication (OWC), operating from 350 to 1550 nm (spanning from ultraviolet to mid-infrared bands), has emerged as a potential solution for mitigating the challenges posed by the escalating demand for bandwidth and communication resources [3]. Traditional OWC-based technologies such as light-fidelity (LiFi) and visible light communication (VLC) target applications in which high to very-high data rates are needed [4]. On the other hand, optical camera communication (OCC) is a subtype of optical wireless communication (OWC) technology that utilizes image sensors as receivers operating in either the infrared (IR) or visible bands. In comparison to other OWC technologies, OCC presents several advantages. First, it allows the use of current component-off-the-shelf cameras present in many devices as receivers, without additional adaptation. Second, these devices offer inherent spatial division multiplexing (SDMA) capabilities thanks to the use of image-forming optics and a large number of pixels. As a result, OCC-enabled devicescan simultaneously collect information from a massive number of endpoints, making them suitable for communication and various other applications. This latter feature fits into one of the joint communication and sensing (JC&S) paradigms of 6G, which integrates sensing and communications operations on a single piece of hardware, while using the same spectral resources [5]. Due to its cost-effectiveness and highly aggregated information-carrying capability, OCC has garnered significant attention in indoor and outdoor domains, including for intelligent transportation and positioning systems [6], underwater communication [7], and IoT connectivity [8]. While OCC appears to be a promising solution for addressing challenges in wireless communication systems, it presents some limitations. These include, but are not limited to, a low data rate resulting from the receiver's low sampling rate, reduced dynamic range, high power consumption, and large latency [9]. The latest advancements in alternative camera technologies, such as event, multispectral, hyperspectral, and thermal, have opened up new possibilities in the field of OCC. The bio-inspired technology of \"silicon retinas\", proposed in [10], mimics the neural architecture of the eye, introducing a new philosophy on how visual information can be gathered. These \"silicon retinas\", which have received other nomenclatures such as event-based cameras or dynamic vision sensors (DVS), respond asynchronously to scene illumination variations at the pixel level, offering high-precision time information and low latency (both in the order of microseconds). In contrast, conventional cameras typically acquire absolute intensity image frames at fixed time intervals. DVS devices measure pixel-wise brightness changes asynchronously rather than measuring absolute brightness at a constant rate [11]. Since DVS presents a sparse, fast, and highly dynamic range output, they can overcome the limitations of frame-based cameras [12]. In this study, an optical communication system utilizing an LED as the transmitter and an event camera as the receiver is comprehensively evaluated.
