Abstract
An RF unit receives multicarrier signals via a plurality of antennas. A division unit divides the multicarrier signals received into a plurality of groups in the frequency domain. The division unit acquires the channel quality for each subcarrier, contained in the multicarrier signal, in the frequency domain, and defines the plurality of groups according to the channel quality. The processing unit performs adaptive array signal processing for each of the divided groups.
Claims3
A radio apparatus, comprising:
- a receiver configured to receive multicarrier signals via a plurality of antennas;
- a division unit configured to divide the multicarrier signals received by said receiver, into a plurality of groups in a frequency domain;
- and
- a processing unit configured to perform adaptive array signal processing for each of the groups divided by said division unit,
- wherein said division unit acquires a channel quality for each subcarrier, in the frequency domain, contained in the multicarrier signal and sets the plurality of groups according to the channel quality such that the quality of subcarriers in a group are mapped to the same predefined stage and the group includes a set of subcarriers adjacent to each other.
