“…Note that (15) is a fractional programming (FP) with the objective function being a sum of multiple ratios. Remark 1: The conventional alternating optimization approach usually decomposes the original nonconvex problem (14) into two subproblems in p r and p c , respectively [11]- [13], [32]- [34]. Although the subproblems are simpler than the original problem, they are still nonconvex and require convex relaxation techniques to solve.…”

“…Recently, the IA techniques have been applied to effectively mitigate the ISI in the spectrum sharing radar and communication systems [ 39 , 40 , 41 ]. In [ 39 ], a joint pre-coder and post-coder design based on the IA principle was proposed for spectrum sharing between MIMO radar and MIMO communication systems and another joint transmit and receive beamformer design with a two-tier alternating optimization algorithm was proposed for spectrum shared MIMO radar and MIMO communication systems in [ 40 ]. An ergodic IA method for interference elimination in spectrum shared MIMO radar and multi-user MIMO communication systems was proposed in [ 41 ].…”

“…An ergodic IA method for interference elimination in spectrum shared MIMO radar and multi-user MIMO communication systems was proposed in [ 41 ]. However, the conventional IA-based ISI mitigation techniques in [ 39 , 40 , 41 ] considered only K -user interference channel in communication systems even though most commercial wireless communication systems consist of BSs and multiple user equipments (UEs) which are belong to a certain BS. In addition, the OIA technique has not been applied to spectrum-shared MIMO radar and MIMO wireless communication systems so far in the literature.…”

“…To eliminate the mutual interference, the authors in [4], [5] have explored the nullspace projection approach, with the main idea of projecting the radar signal into the null-space of the interference channels between the communication and radar systems. In [6]- [10], the authors have achieved peaceful coexistence through the careful design of the transmitter signal waveform of both radar and communication to eliminate the mutual interference between the two systems. Up to the best of our knowledge, this is the first trial to leverage energy harvesting (EH) concept to CRC systems (CRCEH).…”
