An encoder and decoder using LDPC-CC which avoid lowering the transmission efficiency of information while not deteriorating error correction performance, even at termination; and an encoding method of the same. A termination sequence length determining unit determines the sequence length of a termination sequence transmitted added to the end of an information sequence, according to the information length (information size) and encoding rate of the information sequence. A parity calculation unit carries out LDPC-CC coding on the information sequence and the known-information sequence necessary for generating a termination sequence of the determined termination sequence length, and calculates a parity sequence.

There are an updating method of an electronic tag and an update system of the electronic tag performed by the electronic tag which displays sorting information, and a controller and an access point disposed inside a vehicle such as a truck. The controller requests an external server to transmit information on the electronic tag, and the sorting information corresponding to information on a parcel to which the electronic tag is fixed, and transmits the obtained sorting information to the access point. Further, the access point transmits the sorting information to the electronic tag, and the electronic tag updates the display of the sorting information. In this manner, the electronic tag can be updated by using an idle time during delivery.

Electronic tag updating method and electronic tag update system

In an information providing terminal, a half mirror, which reflects display content of a third display panel toward an operator and causes incident light of a third camera to pass therethrough, is obliquely attached to a part above a fourth display panel by 45&#xb0; with respect to a horizontal direction. The third camera is disposed behind the half mirror. The operator has a conversation with a user while viewing a facial picture of the user which is projected by the third display panel and is reflected in the half mirror. The third camera disposed at a back of the half mirror images a facial picture of the operator from the front over the half mirror. At this time, the facial picture of the operator, which faces the front, is projected onto a first display panel of an information displaying terminal.

Information displaying system and information providing terminal

It is possible to provide a sense of realism that a user actually faces a communication partner and to accurately and simply transmit information. In information display system (), first display panel () displays a face and a part of an upper body of an operator op captured by third camera () and second display panel () displays hands of operator op captured by fourth camera () in information display terminal (). In information provision terminal (), third display panel () displays a face of the user captured by first camera (), and fourth display panel () displays hands of the user captured by second camera ().

A communication apparatus repeatedly outputs a first multi-carrier signal SS during predetermined periods T1, T2, T3, . . . , and outputs a second multi-carrier signal RS whose phase vector is different from that of the first multi-carrier signal SS, at a predetermined timing based on the first multi-carrier signal SS. The communication apparatus further detects the second multi-carrier signal RS output from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.

Communication apparatus, integrated circuit, and communication method

In communication method for communicating via a transmission channel to which first communication apparatuses communicating based on a first communication system, second communication apparatuses communicating based on a second communication system, and third communication apparatuses communicating based on a third communication system are connected, a data transmission domain and a notification domain for notifying a data transmission within the data transmission domain are allocated to the first communication apparatuses, the second communication apparatuses, and the third communication apparatuses, respectively. In the communication method, notices of the data transmission for each of the first communication apparatuses, the second communication apparatuses and the third communication apparatuses are transmitted within the notification domain, and the data transmission domain is reallocated in accordance with the notices transmitted from the first, second and third communication apparatuses.

A transmitted digital signal from a digital signal processor is converted into an analog signal at an analog circuit, and then transmitted from transmission lines via a communication transformer. A communication apparatus has a plurality of communication modes that perform communication in different communication ranges. A controller in the digital signal processor changes an output level of the transmitted signal according to the communication modes. More specifically, the controller detects communication quality of the transmitted signal and lowers the output level of the transmitted signal within a range where the detected communication quality does not fall below predetermined quality.

Communication apparatus and communication method

Within a domain of a master device, devices that share a power line as a communications medium monitor signal detection windows to sense network status. The devices transmit sensed network status to the master device. The master device allocates channel resources based on the network statuses communicated by the devices within the domain.

Managing coexistence on a shared power line medium

A communication apparatus repeatedly outputs a first multi-carrier signal SS during predetermined periods T, T, T, . . . , and outputs a second multi-carrier signal RS whose phase vector is different from that of the first multi-carrier signal SS, at a predetermined timing based on the first multi-carrier signal SS. The communication apparatus further detects the second multi-carrier signal RS output from another communication apparatus, which uses a different communication method from the communication apparatus. Accordingly, both communication apparatuses can differentiate the first multi-carrier signal SS from the second multi-carrier signal RS without performing relatively cumbersome modulation and other processes.

A first communication apparatustransmits a pilot signal which was generated by a pilot signal generation section, at predetermined timing, and detects an unbalance component of a transmission lineat the time of pilot signal transmission in an unbalance component detection section, and controls a transmission signal in such a manner that an unbalance component is reduced by a transmission control sectionon the basis of the detected unbalance component.
