RADIO RECEIVER AND INVERSE DIFFUSER

摘要

PROBLEM TO BE SOLVED: To attain flexible modularization without complicating the configuration of hardware by providing a multiplexing means which multiplexes a discrete signal, an inverse multiplexing means which restores the discrete signal and an estimation processing means which estimates the instantaneous value and generates a receiving wave. SOLUTION: Every A/D converter 83 of an A/D conversion board 80 fetches the diffusion signal that is obtained at every front end part 145 and over- sampling cyclically the diffusion signal to individually generate a discrete signal. A multiplexer 84 multiplexes the discrete signal to generate a multiplexed discrete signal and transmits it to a line 82. A demultiplexer 85 of a receiver board 81 applies an inverse multiplexing processing to the multiplexed discrete signal to restore the discrete signal and gives it to an interpolation filter 86. These discrete signals undergo the interpolation processing (estimation processing) via the filter 86, are restored and given to a receiving part 147 in parallel to each other. The number of lines 82 is reduced less than the number of antennas 141.
