Abstract: An example method may include configuring a pattern of a sounding packet of a first wireless node in a resource space. Configuring the pattern may include assigning first precoders to a first subset of the resource space for a first antenna sector of the first wireless node; and assigning second precoders to a second subset of the resource space for a second antenna sector of the first wireless node. The method may include wirelessly transmitting the sounding packet with the configured pattern to a second wireless node. The method may include transmitting data packets from the first wireless node to the second wireless node according to one or more transmission parameters that are at least one of received from the second wireless node or determined based on channel state information (CSI) feedback received from the second wireless node.

Abstract: 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.
