Abstract
A methodis provided to mitigate DC offset in a sign bit correlator associated with a packet detection circuit. The input sign pattern is monitored; and if a long run of the same sign is seen, a sign bit is replaced with a bit generated using a desired pseudorandom noise (PN) sequence. This ensures that the correlator only reacts substantially to correlations that are not due to DC offset.
