Abstract
A method and apparatus is disclosed for minimizing multipath interference in wireless communication systems. A system comprises at least one transmitter and at least one receiver. In the transmitter, transmission beam parameters are dynamically modified using pseudo-random dithering or a sweeping function. The receiver receives an information signal regarding beam parameters or monitors the beam parameters and adjusts its receiving parameters accordingly to optimize its communication link. In an alternate embodiment, the receiver generates and sends feed back information to the transmitter wherein the feed back information may be used to modify beam parameters or perform other functions.
