“…Researchers at Mazda Motor Corp. presented a vehicle-to-vehicle communication and ranging system based on the ranging capabilities of spread spectrum (SS) named "SS communication radar" [29], [35]. A car equipped with this system can range others not equipped by measuring the start of the returned PN code as given by the correlation peak.…”

Abstract-The aim of this work is to study the application of Ultra Wideband (UWB) technology to perform biomedical sensing and vital signs monitoring in humans. Among the numerous signals that can be measured, the heart rate (HR) is chosen as the first objective due to its importance. The research is pointed towards the development of a technique that can allow both, radar sensing and communications using the same UWB transceiver. Such a sensor, could use UWB radar principles to measure the heart beat rate and UWB communication standards to transmit these measurements. Readily available commercial transceivers with minor adaptations will be considered as possible to solve for the physical layer. Signal processing for target detection will be done at higher levels. Having sensors with such "duo" properties can make them ideal nodes for wearable computing, as well as sensor and body area networks.Index Terms-Ultra wideband radar, ultra wideband communications, heart rate, contact-less vital signs monitoring, heart rate variability (HRV).

“…The radar-communications system or RadCom system, which is a part of integrated sensing and communication (ISAC), was first proposed by M. Uchida, Y. Kagawa, and A. Okuno [5] and has been the subject of many studies for years (see for example [1], [5]- [11]) but did not lead to the development of any prototypes so far. A joint radar communication system based on FMCW radar was proposed by P. Barrenechea, F. Elferink, and J. Janssen [6] and C.-H. Wang and O. Altintas [7].…”

Vehicular Communications Over OFDM Radar Sensing in the 77 GHz mmWave Band

Radar detection and vehicle-to-everything (V2X) communication are two advanced driverassistance system (ADAS) functions used to improve the safety of the road users and their driving experience. However, the proliferation of radars on vehicles and the functionalities expected for V2X cause several issues like interference and insufficient communication flow. To address these challenges and optimize the use of the electromagnetic spectrum, the mutualization of communication and radar detection functions in the same component using millimeter-wave (mmWave) is proposed. As orthogonal frequency-division multiplexing (OFDM) waveform seems to be the most suitable waveform to enable this cooperation, we propose to investigate the performance of OFDM radar compared to that of current frequency-modulated continuous wave (FMCW) radar. We simulate and analyse the signal-to-noise ratio (SNR) and the probability of detection (PD) of OFDM radar based on the parameters of a current mid-range automotive FMCW corner radar. We observe that FMCW radar has better SNR and PD than OFDM radar under these conditions. However, by applying a coherent integration scheme on receive, the results obtained show that good performance of OFDM radar can be achieved. To check the effect of the parameters used on the communication performance, we provide graphs of the Bit Error Rate (BER). These graphs show that the BER do not suffer from these parameters but rather that they can be beneficial to the communication.

“…The idea of combining a radar and a communication system on the same platform was studied in [1]. Incipiently the most evident hurdle is that radars and communication systems are separated because of different frequency ranges.…”

Two novel schemes are proposed to synthesize highresolution range profile (HRRP) based on co-located multiple-input multiple-output (MIMO) system in the context of the joint radar and communication system. The difference between two schemes is the pattern of selecting pulses, which depends on the demand for the velocity information. The system, a type of frequency diverse array (FDA), takes full advantage of the phase-coded orthogonal frequency division multiplexing (OFDM) signal. Furthermore, the complete discrete form of the phase-coded OFDM echoes is utilized to derive the HRRP processing. The velocity estimation in the second scheme aims to eliminate velocity ambiguity, and high velocity can be retrieved exactly. Meanwhile, the imaging method is investigated with random frequency coding applied to an array. The desired performance of resolving velocity ambiguity and suppressing noise is shown by means of comparisons with previous work. The advantages in the radar imaging and the significance of the work are concluded in the end.
