ABSTRACT:
In accordance with a particular embodiment of the present invention, a method is offered that includes characterizing a data correlation matrix for an idle pattern offline in a filter environment and, further, using a static adaptive control scheme with a static value of a data-pattern compensation matrix to achieve a compensated adaptive equalizer control. In more specific embodiments, the adaptive control scheme is used with a ZF adaptation scheme in conjunction with a constant adaptation matrix. In other embodiments, the adaptive control scheme is used with a fast steepest-descent method using a variable adaptation matrix. In still other embodiments, the adaptive control scheme is used with a constant adaptation matrix, whereby a value of is statically calculated. If the adaptive control scheme is used with a decoupling matrix, a value of is statically calculated. An inverter is used between the data correlation matrix and the data-pattern compensation matrix.
