A decision feedback equalizer includes a chip estimate buffer that forms
chip estimates into a vector. A CCK decoder decodes the vector of chip
estimates, and a CCK encoder, connected with the CCK decoder, re-encodes
the vector of chip estimates into a valid CCK code word. At the same
time, a chip slicer provides direct sliced chips from the chip estimates.
An update module then forms a hybrid vector from the valid CCK code-word
and the direct sliced chips for input to the feedback filter of the
decision feedback equalizer. The hybrid feedback filter input vector
reflects the CCK coding gain of its re-encoded portion thereby reducing
the estimated chip error rate to improve the performance of the decision
feedback equalizer.
