“…This bandwidth could thus be increased using OFDM, but in this case, the clock recovery PLL, on which the distance measurement is based, would not work anymore. Consequently, moving toward OFDM to reach high data rates would require to change the range-finding method and use, for example, pilot symbols based techniques as proposed in [37].…”

Visible light communication could be an interesting complement to the IEEE 802.11p-based vehicle-to-vehicle communication systems that are sensitive to interferences and delays in dense traffic scenarios such as platooning. Visible light could also provide a redundant distance measure that is crucial for path control in this application. In this paper, a system called visible light communication rangefinder and performing simultaneously vehicle-to-vehicle communication and range-finding using the headlamps and taillights is proposed for the first time. By exchanging a clock signal contained in Manchester-encoded signals, both the following and leading vehicles can share information and estimate their inter-distance through phase-shift measurement. The system is first presented theoretically and it is shown in particular that the Doppler effect has no significant impact on both functions. Then, it is modeled and validated using Simulink. Finally, both the range-finding and communication function are validated experimentally. The rangefinding function is functional up to 25 m, and has a resolution of around 24 cm at 10 m, whereas the communication function provides a 500 kbps link with a BER below 10 −6 up to 30 m.

“…The use of waveform-domain NOMA scheme superimposing FMCW and OFDM waveforms to support joint radar-sensing and communication is firstly proposed by authors in [18]. Here, the superiority of the proposed NOMA scheme over the conventional OFDM scheme for JRC [19] is demonstrated. The proposed architecture separately performs radar-sensing and communication functions using the same radio resources non-orthogonally and leverages the information obtained from radar process to the communication functionality.…”

“…In this section, the radar-sensing and communication performance of the proposed NOMA scheme is compared with the OFDM scheme with pilots for JRC systems proposed in [19]. Comb-type pilot design is used for the compared scheme and pilot spacings in frequency ( ) and time ( ) is arranged as follows [43]:…”

“…The other use case is the implementation of the proposed NOMA concept including frequency modulated continuous-wave (FMCW) and OFDM waveforms in joint radar-sensing and communication, which is presented in [18]. The proposed NOMA scheme for the specific use case is compared with the existing OFDM JRC system presented in [19]. It is shown that proposed scheme outperforms in terms of both radar-sensing and communication functionality.…”

“…Effective block error rate (BLER) performance of the proposed NOMA scheme in the power-balanced regime is demonstrated by comparing to the conventional NOMA scheme with the same waveform. • The superiority of the proposed NOMA scheme for joint radar-sensing and communication, which is firstly introduced in [18] by authors, is demonstrated in terms of ambiguity in radar-sensing functionality, channel estimation mean-square error (MSE) and bit-error rate (BER) performance by comparing with the existing OFDM JRC system proposed in [19].…”
