Latest Patents

Khaled Ardah holds a patent for a spatial filtering technique. This method involves updating spatial filters in a radio network that comprises at least two transmit nodes, each in radio communication with at least one receive node. The process includes transmitting first reference signals precoded by a first spatial filter and receiving second reference signals precoded using a second spatial filter. The second spatial filter is dependent on a channel estimate based on the transmitted first reference signals. The method also involves recomputing the error matrix for each receive node and updating the first spatial filter accordingly. This innovative technique aims to improve the performance of MIMO radio channels.
