摘要： It is possible to provide a radio communication system, a radio base station device, and a radio terminal device capable of reducing the power consumption in a radio terminal device without thinning pilot signals used for measuring upstream line quality. In the radio base station device (100) used in a radio communication system using different frequency bands for the upstream line and the downstream line, an upstream line pilot generation unit (115) forms a CQI measuring pilot signal and an upstream line RF unit (105) transmits the communication quality measuring pilot signal by using the upstream line use frequency band in the upstream line pilot transmission section. Thus, the upstream communication quality measuring pilot signal used by the radio base station device (100) to measure the line quality is transmitted by using the upstream line frequency band and accordingly, it is possible to reduce the power consumption in the radio terminal device.

摘要： Disclosed are an encoding device and a decoding device which can effectively reduce the decoding failure frequency in LDPC encoding/decoding. A loss correction encoding device (120) includes a padding unit (121) which adds a padding packet to an information packet sequence; an interleave unit (122) which rearranges the padding packet and the information packet; and a loss correction encoding unit (123) which performs loss correction encoding for the packet string after the interleave. The interleave unit (122) rearranges the padding packet and the information packet according to variable nodes constituting a minimum stopping set of the inspection matrix which defines a low-density parity inspection code. The interleave unit (122) uses such a rearrangement pattern that avoids a loss correction failure by the minimum stopping set of the LDPC inspection matrix so as to reduce the probability of the loss correction failure by the minimum stopping set.

摘要： There is provided an encoder that provides a termination sequence with a simple structure for LDPC-CC encoding and reduces an amount of the termination sequence transmitted to a transmission line. The LDPC-CC encoder (200) connects a first encoder (230) to a second encoder (240) to perform encoding and thereby carry out LDPC-CC encoding, the first encoder (230) performing encoding based on an partial parity check matrix for information bits (110) obtained by extracting a sequence corresponding to the information bits in a parity check matrix (100) and the second encoder (240) performing encoding based on a partial parity check matrix for parity bits (120) obtained by extracting a sequence corresponding to the parity bits in the parity check matrix (100). A termination sequence generator (210) generates a termination sequence including the same number of bits as the memory length of the first encoder (230) and provides the generated termination sequence as an input sequence.

摘要： An MIMO receiver and MIMO communication system which can have a small hardware scale even if the number of antennas used for MIMO communication. In a radio communication device (200), a receiving section (220) receives a spatially multiplexed signal generated by mutually-different and spatially multiplexing transmission signals, a first signal demultiplexing section (230) subjects a linear operation to the received spatial multiplexed signal to demultiplex the spatial multiplexed signal, and a second signal demultiplexing section (240) demultiplexer the demultiplexed spatially multiplexed signal into the transmission signals. When the received signal is demultiplexed by a single demultiplexing, as the number of multiplexed spatial multiplexed signal increases, the demultiplexer becomes complicated, and the hardware scale increases. When the received signal is demultiplexed by a plurality of demultiplexings, the hardware scale is relatively small.
