摘要： In a cellular-telephone-system base-station receiver's channelizer (111), frequency translation of the outputs of a filter bank (fig. 5) implemented in fast-Fourier-transform circuitry (453, 455, 460) is achieved by rotating the correspondence between FFT input elements and the filter coefficients by which multipliers (437) multiply incoming samples to produce them. Specifically, a storage-address generator (482) directs that corresponding FFT input elements of successive FFT operations be stored in the same locations in an input-data memory (451). To retrieve those values for use in the DFT operation, however, a fetch-address generator (484) employs a modulo-K adder (488) to impose a changing offset so that the starting address for retrieval of each FFT operation's input record changes between FFT operations by the filter bank's decimation rate M. An FFT-implemented combiner (131) similarly rotates computation values to phase align successive wavelets that it adds together to generate modulated carriers in a multi-channel output signal.

摘要： A physically compact, multichannel wireless communication transceiver architecture employs overlap and add or polyphase signal processing functionality, previously applied to narrowband speech analysis research, for wideband signal processing. A receiver section receives a plurality of multiple frequency communication channels and outputs digital signals representative of the contents of the plurality of multiple frequency communication channels. The receiver section contains an FFT-based channelizer that processes the digital signals output by a wideband digital receiver and couples respective channel outputs to a first plurality of digital signal processor units, which process (e.g. demodulate) respective ones of the digital channel signals and supply processed ones of the digital channel signals at respective output ports for distribution to an attendant voice/data network. On the transmit side, a transmit section contains a plurality of digital signal processors, respectively associated with respective ones of a plurality of incoming (voice/data) communication signals to be transmitted over respectively different frequency channels. Their processed (modulated, encoded) outputs are supplied to an inverse FFT combiner. The FFT combiner supplies a combined multichannel signal to a wideband transmitter which transmits a multiple frequency communication channel signal. Each of the channelizer and combiner may be implemented using overlap and add or polyphase filtering.

摘要： A digital signal processing apparatus for frequency multiplexing and demultiplexing of narrow band FDM signals has a first block fine processing stage (11) connected in series to a first block coarse processing stage (16, 17) and in parallel therewith a second block fine processing stage (11a) connected in series to a second block coarse processing stage (16, 17). The two stages 11 and 11a are coupled together at one side remote from the two coarse processing stages (16, 17) to provide a first port (14) and the stages (16 and 17) at the side remote from the port (14) provide a plurality of ports (15). Each stage (11, 11a) is a FIR lowpass filter and each stage (16, 17) incorporates a polyphase filter (16) in connection with a Fast Fourier Transform Unit (17).
