Abstract
A detector circuit for indicating the chip rate of a direct sequence frequency hopped data transmission signal. The wide band input signal is channelized into L adjacent sub-bands and each sub-band signal is multiplied by a delayed copy of itself and then hard limited, after which all the hard limited product signals are totalized to give a resultant signal representative of the chip rate.
