*5.5. Comparison with Existing Works*

A performance comparison of the proposed system is compared with the existing OFDM-based works in Table 4. In most of the experimental demonstrations for the convergence of communications and sensing, the OFDM waveform is evaluated for the sensing performance only. Since the speed resolution is linked with the observation time, higher speed resolution can be realized with longer observation intervals, as shown in Table 4.
