Abstract
A communication processor in a receiving device includes a chip equalizer, a correction matrix calculating unit, and a correction unit. The chip equalizer equalizes a plurality of reception signal sequences received via an antenna. The correction matrix calculating unit calculates a correction matrix by using a channel matrix, a weight of an equalizer, a power ratio of a pilot signal to a reception signal, a number of multi codes, and a spreading factor of the reception signal sequences. The correction unit corrects, by using the correction matrix, the reception signal sequences equalized by the chip equalizer.
Claims10
A receiving device comprising:
- an equalizer that equalizes a plurality of reception signal sequences received via an antenna;
- a calculating unit that calculates a correction matrix by using a channel matrix, a weight of the equalizer, a power ratio Ec/Ior of a pilot signal power Ec to a reception signal power Ior, a number of multi-codes, and a spreading factor of the reception signal sequences;
- and
- a correction unit that corrects, by using the correction matrix, the reception signal sequences equalized by the equalizer.
A receiving process method comprising:
- calculating, performed by a processor, a correction matrix by using a channel matrix, a weight of an equalizer, a power ratio Ec/Ior of a pilot signal power Ec to a reception signal power Ior, a number of multi-codes, and a spreading factor of reception signal sequences;
- equalizing, performed by the equalizer, a plurality of reception signal sequences received via an antenna;
- and
- correcting, performed by the processor by using the correction matrix, the equalized reception signal sequences.
