The Direction of Arrival (DOA) algorithms can estimate the incident angles of all the received signals impinging on the array. These algorithms give the DOAs of all the relevant signals of the user sources and interference sources. However, they are not capable of distinguish and identify which one is the direction of the desired user. In this paper, we propose to use a reference signal which is known...
Motorola has developed a 20 MHz experimental wide-area mobile multi-antenna system at 3.5 GHz for characterizing the spatial channel. With this system, simultaneous channel measurements were taken using both a uniform linear array (ULA) and an array of two cross-polarized (XP) antennas for locations near the Motorola Schaumburg campus. The ULA consists of eight vertically-polarized elements with half...
This paper presents a multiple-input multiple-output (MIMO) space-time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. The model is based on a one-ring scattering assumption. This MIMO model provides statistics of the time of arrival (TOA) and direction of arrival (DOA). It is assumed that there is no line of sight (LOS) between the transmitter...
