In this paper, we study the impact of time-frequency resource scheduling on the performance of an orthogonal frequency-division multiplexing (OFDM)-based radar receiver for joint mobile radio and radar networks. Our results illustrate how the sparse distribution of resources in the time-frequency grid, as used for orthogonal frequency-division multiple access (OFDMA), affects the cost function of a maximum-likelihood estimator. Based on our results, we provide a simple set of rules for the design of resource scheduling schemes in joint networks. Furthermore, we reveal that radar sensing with OFDM can benefit from multiple algorithms and procedures already employed in mobile communication standards, such as synchronization and error correction.
