ELECTRONICS LETTERS 2015年 第3期51卷 296-U98页
作者: Egan, M. Czech Tech Univ Fac Elect Engn CR-16635 Prague Czech Republic
Multiuser multiple-input-multiple-out (MU-MIMO) plays a key role in the widely adopted 3GPP LTE standard for wireless cellular networks. Although exact and asymptotic sum-rate results are well known, the problem of ob... 详细信息

IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS 2013年 第1期12卷 228-236页
作者: Lee, Sang-Rim Kim, Jin-Sung Moon, Sung-Hyun Kong, Han-Bae Lee, Inkyu Korea Univ Sch Elect Engn Seoul South Korea
In this paper, we analyze the average sum rate of downlink multi-antenna systems with zero-forcing beamforming (ZFBF). In practical implementations, each antenna is equipped with its own power amplifier and is limited... 详细信息
