Abstract: Aspects of a method and system for utilizing tone grouping with Givens rotations to reduce overhead associated with explicit feedback information are presented. In one aspect of the invention, Givens matrices may be utilized to reduce a quantity of information communicated in explicit feedback information via an uplink RF channel. The explicit feedback information may include specifications for a feedback beamforming matrix that may be utilized when transmitting signals via a corresponding downlink RF channel. The feedback beamforming matrix may represent a rotated version of an un-rotated matrix. The Givens matrices may be utilized to apply one or more Givens rotations to un-rotated matrix.

The quantity of information communicated in the explicit feedback information may be further reduced by utilizing tone grouping.

Abstract: Methods and systems for mitigating a voltage standing wave ratio in a transmitter are disclosed and may comprise calibrating an output power of a power amplifier integrated within a chip using a resistor that models an impedance of an antenna that is externally coupled to the amplifier while the antenna is decoupled. The gain and output power of the amplifier may be determined utilizing the known resistance and a voltage that is measured at an input of the power amplifier, or at a number of points prior to the power amplifier. When the antenna may be coupled to the transmitter, the transmitter output power may then be controlled utilizing the voltage measurements prior to the power amplifier to avoid measuring reflected waves in instances when the antenna impedance may vary. The power amplifier may be of a design that comprises reverse isolation to reduce reflected waves from the antenna.

Abstract: An interrupt sensitive extract byte instruction scheme is presented herein. The interrupt sensitive extract by instruction extracts bytes from data, depending on the presence of an interrupt. The extract byte instruction extracts bytes from data in the absence of the interrupt and does not extract bytes in the presence of the interrupt. The interrupt can be triggered by a set of counters that count the number of extracted bytes. By loading the counters with a particular number, the interrupt can be generated when the particular number of data bytes is extracted.
