This paper presents a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) joint radar-communication (RadCom) system and explores its tolerance toward mutual interference. Since OFDM signals are weak toward subcarri

A novel concept of employing BPSK codes to achieve a simultaneous transmission in a 79 GHz FMCW automotive radar is presented in this paper. With a MIMO topology, simultaneous azimuth and elevation measurements become possible by utilizing the angle-

This paper presents an approach that allows the simultaneous radiation of fast chirp waveforms from multiple transmit antennas with perfect orthogonality. In contrast to conventional MIMO concepts, which typically consider one dimension of the signal

A modification of the classical orthogonal frequency division multiplexing signals is discussed that allows for the creation of a set of perfectly orthogonal transmit signals sharing the same bandwidth. These signals can be employed for performing ra

It is well known that OFDM-based systems are susceptible and weak towards subcarrier misalignment, which can lead to erroneous demodulation of the receive signal. In the usage of OFDM Radar-Communication systems, whether within cooperative or non-coo
