<p>Systems and methods are disclosed for estimating impulse responses of multiple channels, e.g., multiple antenna sub-array paths of a base station, in a distributed manner. In one embodiment, a method of operation of a Scalable Estimation Ring (SER) processing component in a SER that operates to estimate impulse responses of corresponding channels is provided. In one embodiment, the method includes, during a first iteration of the SER, receiving a feedback signal for the SER processing component and computing an initial estimate of an impulse response of a corresponding channel based on the feedback signal, removing a contribution of the corresponding channel from the feedback signal based on the initial estimate of the impulse response of the corresponding channel to thereby provide a feedback signal for a next SER processing component in the SER, and outputting the feedback signal for the next SER processing component in the SER.</p> |
