摘要： A transmitter of a communication system includes a spectrum dividing section which divides a transmission signal into a plurality of sub-spectra at a first sampling speed F1 and combines one or more low-speed intermediate composite signals from the divided sub-spectra, and a multiplexing section which multiplexes the intermediate composite signals at a second sampling speed F2 faster than the first sampling speed F1 (F2>F1) and distributes to a broadband. A receiver includes a demultiplexing section which extracts one or more low-speed intermediate composite signals from a reception signal at the second sampling speed F2, and a spectrum combining section which combines the intermediate composite signals at the first sampling speed F1 and extracts the sub-spectra to re-combines the transmission signal.

摘要： An OLT (1) is formed by N optical transceivers (11), one PON control circuit (12), and one selection and distribution circuit (13). An optical transceiver selection control signal (SC) is transferred from the PON control circuit (12) to the selection and distribution circuit (13). The optical transceiver selection control signal (SC) indicates the timing of a discovery window, the timing of a grant, and a logical link identification number of a registered ONU assigned to the grant (a logical link identification number for a logical link with the registered ONU). The selection and distribution circuit (13) selects one optical transceiver (11-s (s is an integer falling within a range of 0 to N−1)) from the optical transceivers (11-0 to 11-N−1) based on the optical transceiver selection control signal (SC) from the PON control circuit (12).

摘要： A radio communication system includes a radio apparatus and a signal processing apparatus that function as a base station, and the radio apparatus includes a channel estimation unit that, on the basis of a radio signal transmitted from a terminal apparatus, estimates channel information relating to a radio transmission path between the radio apparatus and the terminal apparatus; a demodulation unit that performs soft-decision demodulation of the radio signal on the basis of the channel information estimated by the channel estimation unit; a signal switching unit that, depending on the terminal apparatus that transmitted the radio signal, switches an output destination of a log likelihood ratio obtained by the soft-decision modulation between either a first path passing through a decoding unit that decodes the log likelihood ratio or a second path not passing through the decoding unit; and a transmission unit that transmits a signal output from the first path or the second path to the signal processing apparatus.
