主 题：massive MIMO radar-communication coexistence spectrum sharing
摘 要：Frequency spectrum sharing between radar and communication systems has recently attracted substantial *** consider the coexistence between a massive multiple-input multiple-output(MIMO)downlink system and MIMO radar to enable the operation of these two systems with minimal mutual *** an asymptotic analysis,we show that by using more antennas at the base station(BS),we can improve the performance of massive MIMO,while keeping the interference to the radar system ***,if we use a large number of antennas at the BS and make the transmit power inversely proportional to the number of antennas,we can avoid the interference from the massive MIMO system to the radar system,with no compromise in the performance of the massive MIMO ***-form expressions for the probability of detection of the radar system and the downlink spectral efficiency of the massive MIMO system,are ***,we propose a power allocation scheme which selects the transmit powers at the MIMO radar and BS to maximize the probability of detection for the MIMO ***,the optimal power allocation can be determined in *** results provide valuable insights into the practical coexistence between massive MIMO and radar systems.
