Embodiment Construction

[0020] refer to figure 2 , shows a communication system 200 according to an embodiment of the present invention. The communication system 200 of the illustrated embodiment includes a transmitter 210 that transmits information from a signal source 203 to a receiver 220 via wireless communication propagation over a communication channel 201 to a signal receiver 204 . To simplify the discussion for ease of understanding, although shown in the described embodiment as a transmitter and receiver pair, it should be understood that the concepts of the present invention may be used with other communication node configurations such as transceivers, if desired.

[0021] The signal source 203 and the signal receiver 204 may include any kind of information communication system or components. For example, signal source 203 and signal receiver 204 may represent nodes within a data network, such as where signal source 203 comprises a server device (such as a processor-based or computerized s...

Abstract

Systems and methods for antenna configuration selection using weighted outdated channel state information are shown. Outdated channel state information may be used in combination with statistical channel information for estimating channel state information according to embodiments of the invention. For example, by combining channel state information, weighted by its temporal relevance, with statistical information, recent channel performance may be used along with historical performance information for antenna configuration selection. Antenna selection of embodiments may be provided for multiple input multiple output (MIMO) systems, such as wireless systems employing multiple radio frequency chains and multiple antennas.

Description

[0001] related application [0001] The present invention is related to the pending US patent application [US-10609149] "Pre-Processing Systems and Methods for MIMO Antenna Systems", the disclosure of which is hereby incorporated by reference incorporated into this article. technical field [0002] The present invention relates generally to communication systems, and more particularly to antenna configuration selection for communication. Background of the invention [0003] Communication systems are generally constrained by the bandwidth and throughput of the communication channels used in providing the communication. Through the communication channel, the routing media environment experienced by the communication signal when propagating from the base stations communicating with each other is destined to be a limited channel used in communication, such as frequency division channel, time division channel, or code division channel. Those skilled in the art will understand t...
