Abstract: 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.

Abstract: 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.

Abstract: A voltage conversion apparatus converts a voltage of an electricity generator. The voltage conversion apparatus includes a maximum power tracking portion that is adapted to output a voltage which is output by the electricity generator to an external device at a predetermined ratio such that an operation point of the electricity generator tracks an optimal operation point at which power of the electricity generator reaches a maximum level, and a voltage output portion that is adapted to output a voltage which is output by the electricity generator to the external device when the maximum power tracking portion is not being operated normally.
