【 摘 要 】

This paper is concerned with multiplexing gain analysis for millimeter-wave (mmWave) massive MIMO systems with distributed antenna deployment. For a point-to-point mmWave system in which the transmitter and receiver consist of K t and K r subarrays, respectively, an asymptotic multiplexing gain formula is derived when the numbers of antennas at subarrays go to infinity. Specifically, considering that all subchannels have the same average number of propagation paths , the formula shows that by employing the distributed antenna architecture, an exact average maximum multiplexing gain of can be achieved. This result means that compared to the co-located antenna architecture, using the distributed antenna architecture can scale up the multiplexing gain proportionally to K t K r.
