Abstract
A communication apparatus includes: a reception unit that receives a communication signal; a preamble detection unit that detects a preamble pattern from the communication signal; and a transfer processing unit that, when the preamble pattern detected by the preamble detection unit is a predetermined preamble pattern, changes the preamble pattern included in the communication signal in accordance with a predetermined rule, and transfers the changed preamble pattern.
Claims13
A communication apparatus comprising:
- a receiver to receive a communication signal, the communication signal including two or more preamble blocks that are signal regions with which two or more different preamble patterns are associated, respectively, the preamble pattern being stored in one of the preamble blocks;
- a preamble detector to detect a preamble pattern from the communication signal;
- and
- a transfer processor to, when the preamble pattern detected by the preamble detector is a predetermined preamble pattern, remove the detected preamble pattern from the communication signal, and transfer the communication signal while storing, in a second block, a preamble pattern associated with the second block that is a signal region following a first block that is a signal region in which the detected preamble pattern has been stored.
A communication method comprising:
- a step of a first communication apparatus generating and transmitting a communication signal in which a first preamble pattern is stored in a leading preamble block among a plurality of preamble blocks that are regions in each of which a preamble pattern is stored;
- and
- a step of a second communication apparatus that has received the communication signal from the first communication apparatus, the second communication apparatus removing the first preamble pattern, and transferring the communication signal while storing a second preamble pattern different from the first preamble pattern in a preamble block subsequent to the leading preamble block.
A control circuit that controls a communication apparatus to cause the communication apparatus to execute:
- a step of detecting a preamble pattern from a received signal, the received signal including two or more preamble blocks that are signal regions with which two or more different preamble patterns are associated, respectively, the preamble pattern being stored in one of the preamble blocks;
- and
- a step of, when the detected preamble pattern is a predetermined preamble pattern, removing the detected preamble pattern from the received signal, and transferring the received signal while storing, in a second block, a preamble pattern associated with the second block that is a signal region following a first block that is a signal region in which the detected preamble pattern has been stored.
A non-transitory storage medium in which a program for controlling a communication apparatus is stored, the program causing the communication apparatus to execute:
- a step of detecting a preamble pattern from a received signal, the received signal including two or more preamble blocks that are signal regions with which two or more different preamble patterns are associated, respectively, the preamble pattern being stored in one of the preamble blocks;
- and
- a step of, when the detected preamble pattern is a predetermined preamble pattern, removing the detected preamble pattern from the received signal, and transferring the received signal while storing, in a second block, a preamble pattern associated with the second block that is a signal region following a first block that is a signal region in which the detected preamble pattern has been stored.
