DUPLICATE AND SUMMING FILTER FOR BROADBAND COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To provide an architecture of a multi-channel radio communication receiver in small size, whose hardware is more simplified. SOLUTION: The architecture of the multi-channel radio communication receiver uses a duplicate and summing or polyphase signal processing function. A receiver section receives multiplex frequency communication channels and outputs a digital signal representing the contents of the multiplex frequency communication channels. The receiver section processes the digital signal outputted from a broadband digital receiver and includes a channel processing unit on the basis of the FFT that couples respective channel outputs with a digital signal processor, the digital signal processor processes each of digital channel signals and outputs the processed digital channel signal to respective distribution output ports. A transmission section includes digital signal processors and the digital signal processors are related to respective arrival communication signals to be sent via different frequency channels.
