Millimeter wave (mmWave) communication provides high data rates thanks to large arrays at the transmitter and receiver, coupled with large bandwidth channels. Exploiting the arrays is challenging due to the need to configure precoding at the transmitter based on the large frequency selective channel. In this paper, we exploit the power iteration principle and propose a robust analog precoding training...
Unlicensed LTE system holds high potential to effectively offload data traffic/video traffic from the crowded LTE networks. Listen-before-talk is generally necessary for unlicensed LTE to coexist with existing transmissions in the unlicensed band (e.g. wireless LAN). This paper studies the interaction of clear channel assessment (how hard one should listen before talk) and transmit power control (how...
We study antenna training method for millimeter wave MIMO communication systems and develop iterative antenna training (IAT) algorithm and protocols. The newly developed training method features low training overhead as well as low computation complexity, and has great application potential in practice.
