1. An access node, comprising:

  • a first radio module configured to receive, using a first antenna, a transmission including a first signal and a second signal;

    a second radio module configured to receive, using a second antenna, the transmission;

    a memory module; and

    a processor module coupled to the first and second radio modules and the memory module and configured to;

    derive a first local reference signal from the received transmission of the first radio module;

    derive a second local reference signal from the received transmission of the second radio module; and

    estimate one or more channel transfer functions associated with the received transmission, the estimation of the one or more channel transfer functions includingcorrelating at least a portion of an expected reference signal associated with the first signal and at least a portion of an expected reference signal associated with the second signal with corresponding portions of the first and second local reference signals,wherein the at least a portion of the expected reference signal associated with the first signal and the at least a portion of the expected reference signal associated with the second signal are non-orthogonal.
