1. A method for detecting a signal comprising:

  • receiving a signal vector over a plurality of channels;

    determining a channel matrix H that represents at least one of the plurality of channels;

    using an iterative algorithm, determining a change of basis matrix T that when multiplied with the channel matrix H converges to a matrix H*T that is more orthogonal than the channel matrix H, wherein the iterative algorithm is upwardly bounded in a number of iterations by a predetermined maximum value; and

    using the channel matrix H and the change of basis matrix T to detect the received signal vector.
