1. A method for processing signals in a communication system comprising:

  • receiving signals via a plurality of receiving antennas, in which a respective decoder of a plurality of decoders is utilized to decode signals received at a respective receiving antenna;

    decoding in each decoder to calculate respective channel estimation for signals received at a respective receiving antenna for that decoder, wherein the channel estimation is calculated based on preamble data in the signals and a transfer function matrix is generated in each decoder to calculate the respective channel estimation and a square matrix;

    computing a complex-valued rotation factor in each decoder to minimize crosstalk in respect to the calculated channel estimation for that decoder;

    selecting one of the complex-valued rotation factors which produces a least amount of crosstalk based on a preselected computation; and

    transmitting the selected complex-valued rotation factor to a transmitter that transmitted the signals to utilize the selected complex-valued rotation factor for subsequent signals sent to the receiving antennas.
