Title:
PILOT STRUCTURE TO SUPPORT A VIRTUAL DIVERSITY RECEIVER SCHEME
Document Type and Number:
WIPO Patent Application WO/2014/053980
Kind Code:
A3
Abstract:
Devices and methods for providing a pilot structure for a virtual diversity receiver (VDR) scheme are disclosed. In order to improve the performance of a communication network, a VDR scheme is implemented to facilitate the exchange of information between user devices via an intermediary device, such as a base station. The pilot structure supports estimation of channel parameters at the receivers, including true channel taps, as well as estimations of the virtual channels created by the VDR scheme in order to enable the use of receive-diversity signal processing techniques.
