Abstract:
A receiver for a wireless telecommunications system, said receiver comprising:an analog-to-digital converter responsive to an analog signal, said analog-to-digital converter converting the analog signal to a digital signal, said analog signal having a frequency bandwidth capable of including a plurality of separate signals over separate signal channels, said analog-to-digital converter simultaneously converting the separate signals, where the digital signal includes a stream of digital data bits identifying the separate signals simultaneously processed by the analog-to-digital converter; and a digital channelizer responsive to the digital signal from the analog-to-digital converter, said digital channelizer separating the digital signal into the plurality of separate signals, wherein the channelizer includes a plurality of digital sub-band tuners (DSBTs), each DSBT digitally filtering individual carrier data streams from a digital multi-carrier data stream based on a programmable center frequency, and each DSBT further digitally filtering the individual carrier data streams based on a programmable bandwidth.
