MIMO Dual-Functional Radar-Communication Waveform Design With Peak Average Power Ratio Constraint

In this paper, novel Dual-Functional Radar-Communication (DFRC) waveforms with peak average power ratio (PAPR) constraint are designed, which under the multiple-input multiple-output (MIMO) radar-communication system. The DFRC transmitted by multiple antennas can send communication information to many downlink cellular users and detect radar targets simultaneously. An optimization model is established minimize multi-user interference (MUI) PAPR constraint. non-convex quadratically constrained quadratic programs (QCQP) be derived into a convex problem solved using semi-definite relaxation (SDR) technique rank-one approximation. Numerical simulations demonstrate that our proposed achieve better performance in practical scenarios without sacrificing performance.
