Summary: | Dual-function Radar and communication (DFRC) systems accommodate both Radar and communication function-alities by integrating them into a single hardware and using the same waveform. Recently, index modulation that transmits the information bits by activating fewer transmission entities (antennas, sub-carriers, etc.) during data transmission has been employed to improve the performance of DFRC systems. Considering the modified Cramer-Rao bound (MCRB) of the directions of arrival, ranges and velocities of the targets as the metrics, the Radar performance can be improved by selecting the combinations of the sub-carriers and antennas that can be activated. In this paper, to choose the best combination, we solve the multi-objective problem based on the MCRB of the target parameters using the Pareto front technique. This results in a set of non-dominated solutions. At that stage, depending on the user's priorities and practical considerations, one solution belonging to the Pareto front will be chosen. |
