Abstract: Techniques to correct for phase and amplitude mismatches in a radio device in order to maintain channel symmetry when communicating with another device using MIMO radio communication techniques. Correction for the amplitude and phase mismatches among the plurality of transmitters and plurality of receivers of a device may be made at baseband using digital logic (such as in the modem) in the receiver path, the transmitter path or both paths of that device. In a device, amplitude and phase offsets are determined among the plurality of radio transmitter and radio receiver paths by measuring phase and amplitude responses when supplying a signal to a transmitter in a first antenna path of the device and coupling the radio signal from a first antenna to a second antenna path of that device where the signal is downconverted by a receiver associated with the second antenna path, and similarly coupling a signal from the second antenna path to the first antenna path. Measurements are obtained between the first antenna path and each of the other antenna paths when coupling a signal in both directions between them. Phase and amplitude offset correction values are computed from the phase and amplitude measurements during a self-calibration operation or mode of the device, and are used during a run-time operation or mode when processing the baseband transmit and/or receive signals to compensate for the phase and amplitude offsets among the plurality of transceiver paths of a device. Amplitude offset correction may not be necessary (or optional) for certain radio implementations or MIMO radio algorithms. The device may execute the self-calibration mode on device power-up, and then periodically thereafter. Self-calibration may also be performed at the factory on a device.

Abstract: A method and associated system for effectively increasing the number of antenna elements within a multi-element antenna system through computation of a response of "virtual" antenna elements located along an antenna array. The physical elements of the array are positioned sufficiently near each other to enable synthesis of a polynomial or other mathematical expression characterizing the response of the array to receipt of an incident waveform. Values of the responses associated with the virtual antenna elements of the array may then be determined through evaluation of the synthesized polynomial or other expression. The resultant array response values associated with the virtual and physical elements of the array are then provided to an associated receiver for processing.

Abstract: The beam pattern associated with a multi-beam antenna array is adjusted if a first beam of the beam pattern is overloaded. A lobe of a second beam of the beam pattern can be steered away from a main lobe of the first beam. Also, if a user is located in an area covered by a second beam which is adjacent to the first beam, a third beam of the beam pattern can be selected for effectuating communication with the user. If a user is located in an area covered by the first beam, another beam of the beam pattern can be selected for effectuating communication with the user.

Abstract: An adaptive antenna signal identification process to provide increased interference rejection in a wireless data network such as a wireless Local Area Network CLAN), The adaptive antenna is located at an access point and can be steered to various angle of arrival orientations with respect to received signals. Associated radio receiving equipment utilizes two distinct signal detection modes. In a first mode, the directional antenna array is set to have an omni-directional gain pattern. In this mode, certain identification parameters of an initial portion of a received signal are detected, such as a source identifier. If the received signal has not been previously detected, then the antenna array is scanned determine a direction setting that provides a best received signal metric. Once the best directional setting for the received signal, that setting is saved for future use in receiving the same signal. If the received signal has been previously detected, the system instead will steer the directional antenna to the last known best direction for reception for the particular detected signal. As further portions of the same signal are received, such as payload portions of a data frame, the directional antenna array can continue to scan potential new best angles. When the invention is deployed in a relay function, where messages received from a first node are to be forwarded to a second node, the recorded direction of its best reception is retrieved for the second node and used when the antenna array is used to transmit the signal to 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 IP addresses.

Abstract: An adaptive array antenna reception apparatus includes radio reception blocks (102a, 102b, ...102n) which convert RF signals from antenna elements (101a to 101n) into base band signals (118a, 118b, ...118n) and output them. A searcher block (103) detects a path position (timing) for each of the beams of the n antenna elements (101a to 101n) in response to the base band signal converted. A finger block (104) performs de−spreading at the timing detected by the searcher block (103), forms a beam by using adaptive algorithm, and performs maximum−ratio synthesis. Thus, it is possible to distinguish paths from one another even when the paths are overlapped on the temporal axis by the path position (timing). At the stage when delay information has changed, there is no need of re−allocating the paths. This improves beam following characteristic and communication quality.
