Abstract
A subchannel detection system for a wireless communication device is disclosed. The system includes an input interface arranged to receive digital data over a predetermined baseband having a plurality of subchannels a plurality of frequency translators arranged to shift the spectrum of the digital data within a subchannel to the center of the baseband, a plurality of low-pass filters arranged to filter frequencies in the middle of the baseband within a subchannel bandwidth, a plurality of correlators arranged to receive a filtered digital signal and correlate the received signal to a subchannel size, and a processing module arranged to receive data from the plurality of correlators and detect one or more active subchannels. The plurality of frequency translators shift the spectrum of all subchannels in the digital data to the center of the baseband; the shifted spectra are filtered by the plurality of low-pass filters and correlated to individual subchannels.
