Method of detection of signals using an adaptive antenna in a peer-to-peer network
First Claim
1. A mobile station configured to conduct wireless communications comprising:
- a directional antenna configured to receive a message;
the directional antenna configured to suppress the transmission of an acknowledgement message when the message is correctly received, wherein the suppression of the acknowledgement message forces a retransmission of the message;
a controller configured to steer the directional antenna according to a directional angle;
the directional antenna configured to receive the retransmission of the message at the directional angle;
the controller configured to determine the received signal quality of the retransmission of the message; and
the directional antenna configured to suppress the transmission of an acknowledgement message and receive further retransmissions of the message at new directional angles until a desired received signal quality of the message is achieved.

Abstract
An adaptive antenna signal identification process to provide increased interference rejection in a wireless data network, such as a wireless Local Area Network (LAN). An adaptive antenna, such as a directional antenna, can be steered to various angle of arrival orientations. For example, the adaptive antenna can be steered to the last known best direction for reception of a particular detected signal. When the invention is deployed in a relay function, messages received from a first node are forwarded to a second node using a recorded direction of best reception from the second node. Storage of the best antenna angle for propagation to neighbor nodes can be handled by control functions in a manner that is analogous to other router lookup tables, such as being contained in a lookup table that stores Internet Protocol (IP) addresses.
