Abstract
The present disclosure provides a radio communication apparatus, a radio communication system, a radio communication method, and a program capable of demodulating signals at appropriate reception timings. A radio communication apparatus 11 includes: a measurement unit 111 configured to measure delay profiles of a plurality of frequency bands; and a determination unit 112 configured to determine a path timing of a first frequency band f1 based on a time difference between a first time tm1 indicating a time of a maximum amplitude in the first frequency band f1 of the plurality of frequency bands and a second time tm2 indicating a time of a maximum amplitude in a second frequency band f2 of the plurality of frequency bands.
Claims5
A radio communication apparatus comprising:
- a processor;
- and
- memory storing executable instructions that, when executed by the processor, causes the processor to:
- measure delay profiles of a plurality of frequency bands;
- and
- determine a path timing of a first frequency band based on a time difference between a first time indicating a time of a maximum amplitude in the first frequency band of the plurality of frequency bands and a second time indicating a time of a maximum amplitude in a second frequency band of the plurality of frequency bands,
- wherein when the first time is later than the second time and the time difference is larger than a path update threshold, the second time is determined to be the path timing of the first frequency band, and
- wherein when the first time is later than the second time and the time difference is equal to or smaller than the path update threshold, the first time is determined to be the path timing of the first frequency band.
A radio communication apparatus comprising:
- a processor;
- and
- memory storing executable instructions that, when executed by the processor, causes the processor to:
- measure delay profiles of a plurality of frequency bands;
- determine a path timing of a first frequency band based on a time difference between a first time indicating a time of a maximum amplitude in the first frequency band of the plurality of frequency bands and a second time indicating a time of a maximum amplitude in a second frequency band of the plurality of frequency bands;
- and
- judge similarities between the path timing of the first frequency band and a path timing of the second frequency band,
