1. A method comprising:

  • receiving, via L receive antennas, from K transmit antennas, L received versions of a symbol, c, weighted prior to transmission by a transmit weighting vector proportional to [gH]Hermitian, where g is a vector having L components and the superscript Hermitian is the Hermitian operator; and

    weighting the L received versions of the symbol, c, by a weighting factor based on g to generate L weighted received versions of the symbol c,wherein H is a channel estimate matrix having K×

    L elements hkl, corresponding to channels between the K transmit antennas and the L receive antennas,wherein K is greater than one, andwherein L is greater than one.
