  • Publication number: 20230387994
    Abstract: A method includes receiving CSI frames among P CSI frames transmitted from another electronic device. The method includes estimating a CSI from each of the received CSI frames as an available CSI estimate. The method includes identifying an impairment model accounting for inclusion of amplitude or phase errors of an estimated CSI corresponding to a p-th CSI frame among the P CSI frames. The method includes compensating, via the impairment model, for the errors in amplitude and phase of P CSI estimates. Compensating for the errors in amplitude and phase of the P CSI estimates can be based on: approximating a missing CSI estimate based on the available CSI estimates; determining an AGC gain value; or computing the errors in the phase based on a weighted least-squares solution. The method includes estimating a breathing rate of a subject based on different spatial dimensions of the P compensated CSI estimates.
