RECEIVER CAPABLE OF PARALLEL DEMODULATION OF MESSAGES

摘要

A receiver (100) which is capable of receiving in parallel data transmitted at arbitrary frequencies within a radio channel includes: a radio frequency (RF) front-end to convert an RF signal to a digitized signal; a Fast Fourier Transform (FFT) generator (130) coupled to the RF front-end to separate the digitized signal into a plurality of sub-channels; a band of phase locked loops (PLLs)(132) coupled to the FFT generator (130), each PLL operating on a sub-channel with a sub-channel center; and a flag detector (131) coupled to the bank of PLLs (132) to detect variations from the sub-channel center and to recover the usage data transmitted from the end-point.
