Abstract:
A radio receiving apparatus includes an RF front-end unit that performs gain control and downconversion on a received signal, an analog equalizer that performs an analog equalization process on an output signal from the RF front-end unit in accordance with a coefficient of analog equalization, an analog/digital converter that samples and quantizes an output signal from the analog equalizer, a digital equalizer that performs a digital equalization process on an output signal from the analog/digital converter in accordance with a coefficient of digital equalization, and a coefficient-of-equalization calculator that calculates the coefficient of analog equalization and the coefficient of digital equalization by estimating frequency characteristics with use of the output signal from the analog/digital converter.

Claim (Index 4):
The radio receiving apparatus according to  claim 1 , wherein a frame of the received signal contains a first training field, a first channel estimation field, a physical header, a second training field, a second channel estimation field, and a payload, the first training field, the first channel estimation field, and the physical header being transmitted through two or more narrowband channels with a minimum unit of bandwidth, the second training field, the second channel estimation field, and the payload being transmitted on a single wideband channel with a bandwidth wider than the minimum units of bandwidth, the wideband channel being set up by bundling the two or more narrowband channels,\n the coefficient-of-equalization calculation circuitry calculates the coefficient of analog equalization by performing a channel estimation of the narrowband channels with use of the first channel estimation field and calculates the coefficient of digital equalization by performing a channel estimation of the wideband channel with use of the second channel estimation field, the analog equalization circuitry performs an analog equalization process on the physical header, the second training field, the second channel estimation field, and the payload, and the digital equalization circuitry performs a digital equalization process on the payload.
