Özet
ISAC (Integrated Sensing and Communication) technology stands out as a critical approach that enhances bandwidth efficiency and enables next-generation intelligent network applications by combining sensing and communication functions on a common spectrum, waveform, and hardware infrastructure. This study comparatively examines RF-ISAC (Radio Frequency-based ISAC) and O-ISAC (Optical-based ISAC) systems operating in tunnel environments under a unified framework encompassing transmitter, channel, and receiver models. While multi-antenna structures and complex signaling methods are considered in the RF-ISAC model, optical transmission is modeled under the constraints of intensity modulation and direct sensing in the O-ISAC model. Due to the challenging characteristics of tunnel environments, such as limited geometry, multipath propagation, waveguide effects, and direct and off-line-of-sight transitions, physically consistent channel representations have been developed for both systems; thus, it is possible to evaluate sensing and communication performances under the same assumptions. Using simulation parameters consistent with experimental findings in the literature, the relationships between BER (Bit Error Rate) and SNR (Signal to Noise Ratio), detection probability and SNR, range and SNR, and bandwidth and range resolution were analyzed, and the obtained results were evaluated.
