Abstract

Spectrum sharing is an approach to solving the congestion problem in radio frequency (RF) bands. The 3500-3650 MHz band has been allocated in the United States for spectrum sharing between military radar systems and cellular systems. Hence, this paper considers a multiple-input multiple-output (MIMO) radar system and a MIMO communication system sharing the same spectrum band. The performance of the communications system is analyzed by considering interference from the radar with regard to signals reflected at the radar's target. A majority of papers prefer to omit the effect of the target reflection coefficient, which depends on the scattering characteristic of the target. Therefore, in this paper, the target reflection coefficient is integrated, and the scattering effect to the MIMO communications system is analyzed. Also, the power of the transmitted radar waveforms is varied. The direction of the targets is considered, and their impact on the MIMO communication system is analyzed. Using a zeroforcing (ZF) receiver, the bit error rate (BER) of the communication system is simulated.
