1. A method comprising:

  • estimating a phase error for a signal communicated across a multiple antenna communication channel, in which each transmitting antenna and each receiving antenna has a phase noise component for a channel matrix used to calculate phase noise present in the signal; and

    correcting for the phase error by applying phase correction to the signal based on the estimated phase error.
