Joint Optimization Scheme for Subcarrier Selection and Power Allocation in Multicarrier Dual-Function Radar-Communication System

Chenguang Shi et al.

Summary: The article discusses the design of a joint subcarrier selection and power allocation scheme to minimize power consumption in a DFRC system capable of performing radar and communication purposes. A three-step solution technique is developed for the joint optimization scheme, combining cyclic minimization algorithm and Karush-Kuhn-Tuckers optimality conditions. Numerical results validate the theoretical findings and verify the effectiveness of the proposed joint optimization scheme.

Transmit/Receive Beamforming for MIMO-OFDM Based Dual-Function Radar and Communication

Tuanwei Tian et al.

Summary: In this paper, the problem of transmit/receive beamforming in a dual-function radar and communication system is studied, using Kullback-Leibler divergence as design metric and solved through the proposed ADSRP algorithm. Simulation results are provided to evaluate the impact of different QoS requirements and PAPR constraints on power allocation scheme and radar detection performance.

Limited Feedforward Waveform Design for OFDM Dual-Functional Radar-Communications

Musa Furkan Keskin et al.

Summary: The paper discusses the time-frequency waveform design in a radar-communications system to achieve a performance trade-off between radar and communications. It first focuses on radar-optimal waveform design by optimizing subcarrier powers and then investigates the DFRC trade-off waveform design to optimize the communication rate under radar similarity constraint. The proposed JWCSO approach leverages the sparsity and rank-one structure of DFRC waveforms within an alternating maximization framework to achieve near-optimal radar-communications trade-off performance.
