  • Modular digital processing system for telecommunications satellite payloads
    Patent number: 8634414
    Abstract: A telecommunications satellite payload processing system having one or more identical generic integrated processor modules is provided. The number of integrated processor modules can be selected in accordance with the antenna and bandwidth characteristics of a specified mission uplink and downlink in relation to the characteristics of the integrated processor module.
    Type: Grant

  • Digital signal processing apparatus for frequency demultiplexing or multiplexing
    Patent number: 6118794
    Abstract: Digital signal processing apparatus for frequency demultiplexing a wide band channel which converts the data stream into parallel branches by means of serial-to-parallel conversion, and demultiplexing which consists of low pass and high pass fine filtering stages and a coarse filtering stage split among processors across parallel branches. Wideband signals arc processed without expensive processors because of the slower rate in the parallel channels. This may also be used for the inverse function of multiplexing.

  • Digital signal processing apparatus
    Patent number: 5699363
    Abstract: 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).
