This brief considers the transmit designs in spectral coexistence of multiple-input multiple-output (MIMO) communication and MIMO radar systems. A joint optimization of the communication transmit covariance matrix and the radar transmit waveform is designed to maximize the communication rate, with constraints concerning the similarity with a standard radar waveform and the transmit energies of both the radar and the communication system. The original design is constructed by solving two convex optimization problems. Then an algorithm of alternating iterative procedure is developed, whose solutions are provided in closed form. Simulation results are presented to validate the effectiveness of the proposed algorithm.
