Abstract
A receiver includes a sample and hold circuit that receives a signal (continuous time signal) that has been subject to frequency division multiplexing modulation, converts the signal to a discrete time signal, and outputs the discrete time signal, a discrete time filter that receives the signal output from the sample and hold circuit and attenuates a frequency component of a subcarrier different from a specified subcarrier, and a demodulation unit that extracts a digital baseband from a signal that has passed through the discrete time filter to complete a demodulation operation within one data symbol reception period.
Claims16
A receiver apparatus comprising:
- a sampler circuit that samples a signal that has been subject to frequency division multiplexing modulation to convert the signal from a continuous time signal to a discrete time signal;
- a discrete time filter that receives the discrete time signal output from the sampler circuit and attenuates one or more subcarrier frequency components different from a frequency component of a specified subcarrier;
- and
- a demodulation unit that extracts a digital baseband signal from a signal that has passed through the discrete time filter, the demodulation unit completing a demodulation operation within one data symbol reception period.
(canceled)
A reception method comprising:
- receiving a signal that has been subject to frequency division multiplexing modulation as a continuous time signal and outputting a discrete time signal obtained by sampling the continuous time signal for a predetermined sampling period;
- processing the discrete time signal by a discrete time filter to attenuate one or more subcarrier frequency components different from a signal of a specified subcarrier frequency component;
- and
- receiving a signal that has passed through the discrete time filter and performing demodulation processing on the signal.
