An efficient approach to generating the bias resulting during the joint equalization/decoding of a Complementary-Code-Keying (CCK) based system is provided that includes a bias generator system having a plurality of inputs responsive only to feedback filter coefficients, the bias generator generating, based upon said feedback filter coefficients, a plurality of output signals corresponding to the bias of a Fast Walsh Transform system for cancelling the bias.
