In this paper, geometry-based channel models are proposed to describe the topology of generalized distributed antenna systems with cooperative diversity (GDAS-CD). The system architecture comprises M largely separated access points (APs) at one side of the link, and N geographically closed user terminals (UTs) at the other. The UTs are assumed to be operating in cooperative mode to enhance the system...
A geometry-based channel model is proposed to describe the topology of a generalized distributed antenna system with cooperative diversity (GDAS-CD). The system architecture comprises a number of largely separated access points (APs) each with multiple antennas within an AP at one side of the link, and several geographically closed user terminals (UTs) each having multiple antennas within a UT at...
A general framework is presented to study the diversity gains in a wideband directional channel from a physical wave-field perspective. Parameterization of the quantity is based on system-dependent channel characterization, where the propagation channel captured by multipath delays, angles-of-arrival, and angles-of-departure is defined system-dependently. Starting with a simple single-cluster-single-bounce...
