  • Patent number: 8638260
    Abstract: A mechanism for processing beamforming steering matrices in a transceiver system. A plurality of beamforming steering matrices associated with a plurality of subcarriers of an RF signal received at the transceiver system are generated. The beamforming steering matrices are compressed and stored. The beamforming steering matrices may also be grouped or sub-sampled prior to being stored. The beamforming steering matrices are decompressed and ungrouped before being applied to data to be transmitted. Prior to ungrouping the beamforming steering matrices, a phase difference between corresponding beamforming steering vectors of consecutive beamforming steering matrices is determined. Phase rotation is performed on the corresponding beamforming steering vectors based on the determined phase difference associated with the corresponding beamforming steering vectors to improve phase continuity between consecutive beamforming steering matrices.

  • Publication number: 20130287069
    Abstract: Transmitting beamforming can steer a transmitting signal to reduce the interference between spaces of a MIMO system and achieves constructive combination at the receiver. One method of steering matrix calculation includes using singular value decomposition (SVD). Notably, the singular values of SVD, which represent the stream strengths in a MIMO system, are in descending order. In equal modulation, signal strength degradation makes the receive EVM of the latest stream poor and increases the probability of packet error. MMSE can be used to weight the steering vectors of the steering matrix calculated in SVD. This weighting of the singular values can balance the SNR of the streams, thereby improving packet error rate.

  • Patent number: 8422971
    Abstract: A receiver for a wireless communication device comprising a mechanism for performing spur mitigation. A spur mitigation unit of the receiver is operable to determine a current estimate of a spur signal from an ADC output signal using a growing box filter. The spur mitigation unit can determine a power of the current estimate of the spur signal and a power of a previous estimate of the spur signal using a power measurement unit. The spur mitigation unit can determine whether the power of the previous estimate of the spur signal is greater than the power of the current estimate of the spur signal. If the power of the previous spur signal estimate is greater than the power of the current spur signal estimate, the spur mitigation unit can remove the spur signal from the ADC output signal based on the previous spur signal estimate.
