Abstract

Network densification and FD MIMO in cellular networks require higher levels of base station integration while still meeting stringent performance requirements. We present a monolithic transmitter with integrated digital predistortion and calibration which allows RF agile, multi-carrier operation and enables efficient small cell and FD MIMO systems to be realized below 24dBm/antenna.

基于65nm CMOS集成数字预失真的小型蜂窝基站直接转换发射机
蜂窝网络中的网络密度和FD MIMO要求更高水平的基站集成度,同时仍然满足严格的性能要求。我们提出了一种集成数字预失真和校准的单片发射机,它允许射频敏捷,多载波操作,并使高效的小蜂窝和FD MIMO系统能够在24dBm/天线以下实现。
