Estimating the term…
A receiver of a multicarrier communication system capable of reducing inter-subcarrier interfering signals is to be provided. Receive signals received by a receiving antenna are amplified by a receiving amplifier, subjected to quadrature demodulation by multipliers with respect to the respective subcarriers, and band-limited by lowpass filters. The signals band-limited by the lowpass filters are converted into digital signals by A/D converters at a sampling frequency fs. With respect to the receive signals converted into digital signals, interfering signals leaking between subcarriers are estimated by using A/D converted by the A/D converters and are canceled. The receive signals reduced in interfering signals are multiplexed into a single sequence by a multiplexer, and decoded by a decoder into output signals.
