A unique way to determine the position of an UWB tag relative to a single UWB base station is proposed in this paper. The system is made possible by applying the mono-pulse angle measurement concept of the conventional mono-pulse radar to the UWB system to find the direction of the tag. Together with the range measurement based on the time-of-flight of the(More)
This paper considers a multiuser massive multiple-input multiple-output (MIMO) uplink transmission with the help of an N<inf>r</inf>-antenna amplify-and-forward (AF) relay. Assume that the base station (BS) is equipped with a large array of N<inf>d</inf> antennas but supported by a far smaller number, K, of radio-frequency (RF) chains, which greatly reduce(More)
