ABSTRACT:
An OFDM detection apparatus and method for networking devices. First, a sample sequence is taken from the beginning of a newly arrived network packet. Next, a first correlation sequence between the complex conjugate of the sample sequence and the sample sequence with a lag of N samples is formed. In the meantime, a second correlation sequence between the complex conjugate of the sample sequence and the sample sequence with a lag of M samples is also formed. The first and the second correlation sequence are then normalized. Depending on a comparison between the first normalized correlation sequence and a first predetermined threshold as well as another comparison between the second normalized correlation sequence and a second predetermined threshold, the newly arrived network packet is determined accordingly whether it is an OFDM modulated packet.
