Reducing interference in CCK-modulated signals

A receiver for a wireless local area network is provided which has an interference reduction unit for reducing inter-chip interference in a received signal that has been modulated using a complementary code encryption technique such as CCK. 11 The interference reduction unit comprises a decision feedback equalizer comprising a feedforward filter for the reduction of the precursor interference and a feedback filter for the reduction of post-cursor interference in the received signal. DOLLAR A The receiver can perform channel estimation to optimize the filter coefficients during the preambles of the incoming sequence.
