#### Abstract

Co-channel interference and noise power could affect the performance of the MIMO system and can be evaluated with respect to the user’s signal to noise and interference ratio. As a result, the desired transmission rate of the users could be satisfied by consuming more transmit power. Owing to this, a quantum optimization strategy can be utilized in order to minimize the transmit power, as well as to achieve an optimum trade-off within the throughput and the resulting interference and noise. In this study, a constrained quantum optimization algorithm (CQOA) has been implemented in the MIMO-downlink system to reduce the transmit power and computational complexity. An analytical study is conducted along with a comparison between the water filling algorithm-based binary searching algorithm (WFA-BSA), exhaustive algorithm-based water filling algorithm (EWFA), and the CQOA. Finally, simulation results show that the aforementioned methods consume similar total transmit power, however, the computational complexity of the quantum strategy is dramatically low compared to the other methods.
