This article studies and derives beamforming design in a dual-functional radar-communication (DFRC) multiple-input-multiple-output system. We focus on scenario, where the DFRC base station communicates with downlink communication users, imperfect channel state information knowledge, performs target detection, all via same transmit signal. Through careful relaxation procedures, we arrive at suit...

In Part I and II of this three-part tutorial on dual-functional radar-communication (DFRC) design for vehicular networks, we overviewed the basics radar communication systems state art in DFRC respectively. As III tutorial, address issue predictive beamforming vehicle-to-infrastructure (V2I) links without need explicit evolution models. The beam tracking is done with aid signals transmitted by ...

This study proposes a dual-function radar and communication (DFRC) system that utilizes transmission parameters as modulation indexes to transmit data the users while performing sensing its primary function. The proposed technique exploits index (IM) using center frequency of chirps, their bandwidths, polarization states modulate within each chirp. By utilizing combination these indexes, DFRC c...

In this study, a dual-function radar-communications (DFRC) system based on the circulating code array is presented to address contradiction between radar and communications in beam scanning coverage. Processed orthogonal frequency-division multiplexing (OFDM) signal transmitted by as base improve data rate.

Spatial beamforming is an efficient way to realize dual-functional radar-communication (DFRC). In this paper, we study the DFRC design for a general scenario, where base station (BS) simultaneously detects target as multiple-input-multiple-output (MIMO) radar while communicating with multiple multi-antenna communication users (CUs). This necessitates joint transceiver both MIMO and multi-user (...

We study security solutions for dual-functional radar communication (DFRC) systems, which detect the target and communicate with downlink cellular users in millimeter-wave (mmWave) wireless networks simultaneously. Uniquely such scenarios, is regarded as a potential eavesdropper might surveil information sent from base station (BS) to (CUs), that carried by probing signal. Transmit waveform rec...

Dual-function radar-communications (DFRC) systems implement radar and communication functionalities on a single platform. Jointly designing these subsystems can lead to substantial gains in performance as well size, cost, power consumption. In this paper, we propose DFRC system, which utilizes generalized spatial modulation (GSM) realize coexisting communications waveforms. Our proposed GSM-bas...
