Receiving apparatus, receiving method, and terminal unit for use with radio system

Claim 2

A receiving apparatus for receiving a signal that has been spectrum-spread with a spread code, comprising: a searcher for searching for signals received from a plurality of paths; a plurality of fingers for de-spreading the signals received from the plurality of paths, for demodulating data included in the signals, and for determining respective signal intensities of the signals; and a combiner for combining demodulated data provided by the plurality of fingers and for shifting digits of the demodulated data provided by the plurality of fingers based on the respective signal intensities of the signals received from the plurality of paths.

Claim 3

The receiving apparatus as set forth in claim 1, wherein the combiner shifts the digits of the demodulated data after combining the demodulated data.

Claim 4

The receiving apparatus as set forth in claim 1, wherein the combiner shifts the digits of the demodulated data before combining the demodulated data.

Claim 5

A receiving method for receiving a signal that has been spectrum-spread with a spread code, comprising the steps of: searching for a plurality of signals received over a plurality of paths; de-spreading the signals received over the plurality of paths and demodulating data included in the signals using a plurality of fingers; determining respective signal intensities of the signals; and combining demodulated data provided by the plurality of fingers and shifting digits of the demodulated data based on the respective signal intensities of the signals received over the plurality of paths.

Claim 6

A receiving method for receiving a signal that has been spectrum-spread with a spread code, comprising the steps of: searching for a plurality of signals received over a plurality of paths; de-spreading the signals received over the plurality of paths and demodulating data included in the signals using a plurality of fingers; determining respective signal intensities of the signals; and combining demodulated data provided by the plurality of fingers and shifting digits of the demodulated data based on the respective signal intensities of the signals received over the plurality of paths.

Claim 7

The receiving method as set forth in claim 4, wherein the shifting of digits shifts the digits of the demodulated data after combining the demodulated data.

Claim 8

The receiving method as set forth in claim 4, wherein the shifting of digits shifts the digits of the demodulated data before combining the demodulated data.

Claim 9

A terminal unit for use with a radio system for spectrum-spreading a transmission signal with a spread code and providing a resultant signal, transmitting the resultant signal, varying a pattern and a phase of a code sequence of the spread code, and performing a multiple-access operation, comprising: a searcher for searching for signals received over a plurality of paths; a plurality of fingers for de-spreading the signals received from the plurality of paths, for demodulating data included in the signals, and for determining respective signal intensities of the signals; and a combiner for combining demodulated data provided by the plurality of fingers and for shifting digits of the demodulated data provided by the plurality of fingers based on the respective signal intensities of the signals received from the plurality of paths.

Claim 10

A terminal unit for use with a radio system for spectrum-spreading a transmission signal with a spread code and providing a resultant signal, transmitting the resultant signal, varying a pattern and a phase of a code sequence of the spread code, and performing a multiple-access operation, comprising: a searcher for searching for signals received over a plurality of paths; a plurality of fingers for de-spreading the signals received from the plurality of paths, for demodulating data included in the signals, and for determining respective signal intensities of the signals; and a combiner for combining demodulated data provided by the plurality of fingers and for shifting digits of the demodulated data provided by the plurality of fingers based on the respective signal intensities of the signals received from the plurality of paths.

Claim 11

The terminal unit as set forth in claim 7, wherein the combiner shifts the digits of the demodulated data after combining the demodulated data.

Claim 12

The terminal unit as set forth in claim 7, wherein the combiner shifts the digits of the demodulated data before combining the demodulated data.
