According to the present disclosure, a communication device configured to power on a main receiver to receive data from a network includes: a low power receiver configured to receive a wake up packet, including a preamble, from the network and oversample the wake up packet; a circuit arrangement including: a correlator configured to correlate the oversampled portion of the preamble; a delay and adder configured to take an output of the correlator, delay the output of the correlator, and add the output of the correlator back onto itself to produce a delay output; a peak detector configured to detect a peak pattern in the delay output; a demodulator configured to calculate a decoding threshold value to produce a demodulated data; and a packet parser configured to check the demodulated data for a data set in order to selectively output a nonzero signal to power on the main receiver.
