    摘要: Modifying a signal according to a diversity parameter adjustment includes accessing scan parameter values, where a scan parameter describes a scan process. The scan parameter values include diversity parameter vectors, where a diversity parameter vector has a diversity parameter value for each of one or more diversity parameters. The scan process is performed by repeating the following for each diversity parameter vector: modifying a signal according to the diversity parameter values of the diversity parameter vector, where the signal is transmitted from a modifying communication device to a feedback communication device; and receiving a feedback signal reflecting feedback information describing the signal as received by the feedback communication device.

    摘要: A method and system for improving closed loop feedback in transmit diversity communication. In one embodiment of the invention, a predetermined variation of one or more transmit diversity parameters is performed at the transmit transmitter. The receiver compares the transmit diversity parameter values of the received signals to the predetermined variation and transmits to the transmitter a value of a transmit diversity correction parameter. The transmitter may use this correction value to modify the transmit diversity parameter in a subsequent transmission.

    摘要: Calibrating a transmit diversity device includes establishing diversity parameter values of diversity parameters for a plurality of signals, where each signal is transmitted from a channel of the transmit diversity device. The following are performed for each diversity parameter value to yield associations: determining a modification parameter value that yields a diversity parameter value, where a modification parameter value describes modulation of a feature of at least one signal; and associating the modification parameter value with the diversity parameter value to yield an association. Calibration data is generated in accordance with the associations.
