Abstract
A wireless local area network receiver is provided that has an interference reduction unit for reducing interchip interference in a received signal that is modulated using a complementary code keying technique such as CCK-11. The interference reduction unit comprises a decision feedback equalizer that has a feedforward filter for reducing precursor interference and a feedback filter for reducing postcursor interference in the received signal. The receiver may perform channel estimation to optimize the filter coefficients during the preambles of the incoming sequence.
