A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

A loss correction encoding device having an improved capability of loss correction using LDPC-CC includes a rearranging unit that rearranges information data contained in n information packets according to the constraint length Kmax and the encoding rate (q−1)/q of a check polynomial of the loss correction code used in a loss correction encoding unit. Specifically, the rearranging unit rearranges the information data in such a way that continuous Kmax×(q−1) pieces of information data after rearrangement are contained in different information packets. The rearranging unit distributes the information data to information blocks from n information packets, where n satisfies the formula Kmax×(q−1)≤n.

Receiving method with error correction coding with generated dummy data

Disclosed are an encoder, a transmission device, and an encoding method with which the transmission amount is reduced and a deterioration in transmission efficiency is suppressed while improving reception quality when QC-LDPC or a like block encoding is used. A puncture pattern setting unit () searches for a puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of a sub block matrix that forms a check matrix (H) of a QC-LDPC code, and a puncture unit (data reduction unit) () switches the puncture pattern for each integral multiple of the number of columns or for each divisor of the number of columns of the sub block matrix that forms the check matrix of the QC-LDPC code.

Integrated circuit for reception apparatus

The communication apparatus () configured to be installed in a first aircraft () comprises a controller () and a transmitter (). The controller () is configured to acquire resource information and determine a communication condition based on the resource information, the resource information being related to a second aircraft () different from the first aircraft () or to a radio altimeter installed in the second aircraft (). The transmitter () is configured to transmit transmission data to one other communication apparatus installed in the first aircraft (), according to the communication condition.

Communication apparatus and communication control method

A transmitter communicates with a receiver via a satellite station that transmits a signal by a multibeam system. The transmitter includes a scheduler and a transmission unit. The scheduler performs scheduling to determine a time and a wireless channel to transmit data addressed to the receiver based on an area where the receiver is present. The transmission unit transmits a signal of the data addressed to the receiver to the satellite station by the wireless channel determined by the scheduler and at the time determined by the scheduler. The signal transmitted from the transmission unit by an i-th (i is an integer of 1 or larger) wireless channel is transmitted from the satellite station to the receiver by an i-th beam. Frequencies of signals transmitted from the satellite station by respective beams are same.

Transmitter and transmission method

The communication device is installed in an aircraft and is capable of radio communication with a base station on the ground. The communication device comprises a transmitter, a receiver, and a controller. The controller acquires location information of the aircraft at a predetermined time, and communicates with the base station using an allocation pattern of communication resources according to the location information of the aircraft.

System and method for air-to-ground communication involving an aircraft

A low-density parity check convolution code (LDPC-CC) is made, and a signal sequence is sent after being subjected to an error-correcting encodement using the low-density parity check convolution code. In this case, a low-density parity check code of a time-variant period (3g) is created by linear operations of first to 3g-th (letter g designates a positive integer) parity check polynomials and input data.
