1. A method, comprises:
- receiving a plurality measurements of signal-to-interference-plus-noise ratios for one or more receivers, the one or more receivers being coupled to a transmitter via a physical communication link, the physical communication link supporting a plurality of communications channels between the transmitter and the one or more receivers; and
determining a phase of one or more off-diagonal elements of a channel matrix for the physical communication link based on the received plurality of signal-to-interference-plus-noise ratios.

Abstract
An apparatus includes a transmitter configured to transmit symbols to one or more receivers via a plurality of communication channels of a physical communication link. The transmitter is configured to estimate a phase of one or more off-diagonal elements of a channel matrix for the physical communication link based on values of signal-to-interference-plus-noise ratios at the one or more receivers.
