Example operations may include determining a first noise estimate of noise that propagates along a receive path of a device. The operations may further include determining a second noise estimate of the noise and determining a cross-relationship estimate with respect to the noise. In addition, the operations may include adjusting one or more correction filters configured to correct for imbalances between a first branch and a second branch of the receive path. The adjusting may be based on the first noise estimate, the second noise estimate, and the cross-relationship estimate.

Receive path in-phase and quadrature imbalance correction using circuit noise

An example method may include determining a first precoding processing for communication between a beamformer and a beamformee, and transmitting a first sounding signal precoded according to the first precoding processing. The method also includes obtaining first beamforming feedback from the beamformee in response to the first sounding signal, and selecting a second precoding processing for communication between the beamformer and the beamformee. The method also includes obtaining second beamforming feedback from the beamformee based on a second sounding signal from the beamformer preprocessed according to the second precoding processing, and analyzing the first beamforming feedback and the second beamforming feedback. The method additionally includes deriving a quality score of the second precoding processing based on the analysis of the first beamforming feedback and the second beamforming feedback, and selecting the second precoding processing instead of the first precoding processing based on the quality score of the second precoding processing.

Beamforming performance optimization

Modem selection of Reed-Solomon codeword configuration to maximize error-corrected data rate given channel analysis. A lookup table of maximal codeword size given parity bytes and channel MSE allows precomputation.
