Abstract

A reception apparatus includes: a reception section configured to receive a signal modulated by one of a single-carrier scheme and a multi-carrier scheme that are specified by a predetermined standard; a single-carrier demodulation section configured to execute single-carrier demodulation based on the single-carrier scheme onto the signal; a multi-carrier demodulation section configured to execute multi-carrier demodulation based on the multi-carrier scheme onto the signal; and a demodulation control section configured to control such that one of the single-carrier demodulation and the multi-carrier demodulation is tried on the received signal in accordance with a preset predetermined rule.

Claims (48)

1. A reception apparatus comprising:

circuitry configured to

receive a signal modulated by one of a single-carrier scheme and a multi-carrier scheme that are specified by a predetermined standard;

execute single-carrier demodulation based on the single-carrier scheme onto said signal;

execute multi-carrier demodulation based on the multi-carrier scheme onto said signal; and

control such that, in accordance with a preset number of trials in each carrier scheme, one of said single-carrier demodulation and said multi-carrier demodulation is repetitively tried by said preset number of trials for each carrier scheme.

2. The reception apparatus according to claim 1 , wherein said circuitry is configured to first try one of said single-carrier demodulation and said multi-carrier demodulation in accordance with a preset carrier scheme for first trying demodulation.

3. The reception apparatus according to claim 2 , wherein said circuitry is configured to control such that one of said single-carrier demodulation and said multi-carrier demodulation is tried in accordance with a ratio of a number of trials of each carrier scheme to a preset total number of trials.

4. The reception apparatus according to claim 3 , wherein, if said number of trials of said single-carrier demodulation and said multi-carrier demodulation exceeds a preset maximum number of trials, then said circuitry stops the trial of demodulation.

5. The reception apparatus according to claim 1 , wherein, if said number of trials of said single-carrier demodulation and said multi-carrier demodulation exceeds a preset predetermined number of times, then said circuitry stops the trial of demodulation.

6. The reception apparatus according to claim 1 , wherein, if a trial of any one of said single-carrier demodulation and said multi-carrier demodulation is successful, said circuitry is configure to control such that an output of any one of said single-carrier demodulation section and said multi-carrier demodulation section, whichever is successful in the trial of demodulation, is outputted to a post stage.

7. The reception apparatus according to claim 6 , wherein said circuitry is configured to:

execute demodulation processing common to said single-carrier demodulation and said multi-carrier demodulation;

execute demodulation processing unique to said single-carrier demodulation; and

execute demodulation processing unique to said multi-carrier demodulation.

8. A reception method comprising:

receiving a signal modulated by one of a single-carrier scheme and a multi-carrier scheme that are specified by a predetermined standard, by a reception apparatus;

executing single-carrier demodulation based on the single-carrier scheme onto said signal by said reception apparatus;

executing multi-carrier demodulation based on the multi-carrier scheme onto said signal by said reception apparatus; and

controlling such that, in accordance with a preset number of trials in each carrier scheme, one of said single-carrier demodulation and said multi-carrier demodulation is repetitively tried by said preset number of trials for each carrier scheme.

9. A non-transitory computer-readable medium including a program, which when executed by an apparatus, causes the apparatus to:

receive a signal modulated by one of a single-carrier scheme and a multi-carrier scheme that are specified by a predetermined standard;

execute single-carrier demodulation based on the single-carrier scheme onto said signal;

execute multi-carrier demodulation based on the multi-carrier scheme onto said signal; and

control such that, in accordance with a preset number of trials in each carrier scheme, one of said single-carrier demodulation and said multi-carrier demodulation is repetitively tried by said preset number of trials for each carrier scheme.

10. A demodulation apparatus comprising:

circuitry configured to

execute, on a reception signal modulated by one of a single-carrier scheme specified by a predetermined standard and a multi-carrier scheme specified by a predetermined standard, single-carrier demodulation based on said single-carrier scheme;

execute multi-carrier demodulation based on said multi-carrier scheme onto said reception signal; and

control such that, in accordance with a preset number of trials in each carrier scheme, any one of said single-carrier demodulation and said multi-carrier demodulation is repetitively tried by said preset number of trials for each carrier scheme.

11. The demodulation apparatus according to claim 10 , wherein said circuitry is configured to first try one of said single-carrier demodulation and said multi-carrier demodulation in accordance with a preset carrier scheme for first trying demodulation.

12. The demodulation apparatus according to claim 11 , wherein said circuitry is configured to control such that one of said single-carrier demodulation and said multi-carrier demodulation is tried in accordance with a ratio of a number of trials of each carrier scheme to a preset total number of trials.

13. The demodulation apparatus according to claim 12 , wherein, if said number of trials of said single-carrier demodulation and said multi-carrier demodulation exceeds a preset maximum number of trials, then said circuitry stops the trial of demodulation.

14. The demodulation apparatus according to claim 10 , wherein, if said number of trials of said single-carrier demodulation and said multi-carrier demodulation exceeds a preset predetermined number of times, then said circuitry stops the trial of demodulation.

15. The demodulation apparatus according to claim 10 , wherein, if a trial of any one of said single-carrier demodulation and said multi-carrier demodulation is successful, said circuitry is configured to control such that an output of any one of said single-carrier demodulation section and said multi-carrier demodulation section, whichever is successful in the trial of demodulation, is outputted to a post stage.

16. The demodulation apparatus according to claim 15 , wherein said circuitry is configured to:

execute demodulation processing common to said single-carrier demodulation section and said multi-carrier demodulation section;

execute demodulation processing unique to said single-carrier demodulation section; and

execute demodulation processing unique to said multi-carrier demodulation section.

17. A demodulation method comprising:

executing, on a reception signal modulated by one of a single-carrier scheme specified by a predetermined standard and a multi-carrier scheme specified by a predetermined standard, single-carrier demodulation based on said single-carrier scheme by a demodulation apparatus;

executing multi-carrier demodulation based on said multi-carrier scheme onto said reception signal by said demodulation apparatus; and

controlling such that, in accordance with a preset number of trials in each carrier scheme, any one of said single-carrier demodulation and said multi-carrier demodulation is repetitively tried by said preset number of trials for each carrier scheme.
