1. A method for modifying a transmit diversity signal comprising:

  • receiving at least one input parameter;

    calculating at least one virtual parameter based on said at least one input parameter;

    converting said at least one virtual parameter into an actual parameter; and

    modifying a transmit diversity signal based on said actual parameter,wherein said actual parameter has a discrete value having lower resolution than said at least one virtual parameter,wherein converting said at least one virtual parameter into said actual parameter comprises mapping any of a plurality of virtual parameter values to a single actual parameter value, andwherein converting said at least one virtual parameter into said actual parameter comprises truncating said virtual parameter to obtain said actual parameter value, where the truncation is performed according to the formula;


    Φ

    act=b*floor((Φ

    virt+a/b),where Φ

    virt is a virtual parameter,Φ

    act is an actual parameter, anda and b are selected numerical values.
