Not only noise, but interference wave components are thus suppressed, making possible a significant improvement in success rates of demodulation and error correction decoding.
The radio terminal station apparatus then error correction encodes a third packet that is the same packet as the first or second packet; and network decodes the received network encoded packets, by use of the third packet as error correction encoded, to generate decoded packets, thereby performing an error correction decoding process.
A decoder which performs error correction decoding of encoded data constituted by the combination of an outer signal for first error correction and an inner code for second error correction.
In the present invention, a sum-product decoder (17), using an extended parity check matrix Hd in which a matrix D, in which differential modulation in a differential modulator (3) is substituted with a parity check matrix, and an error correcting code-use parity check matrix H, have been combined, carries out soft decision iterative decoding with respect to a received signal s'(t) of a signal receiver (12) in order to perform error correction decoding for an information sequence bi.
A mobile station (mobile terminal) (MS) corrects the error based on the error location information (EI) and performs demodulation through error correction decoding process.
A receiving device which receives a plurality of spatially multiplexed signals from a transmitting device comprises: decoding units (40-1, 40-2) which carry out error correction decoding on the received signals and outputs a coding bit post-LLR and a coding bit external LLR; replica generation units (41-1, 42-2) which generate transmission signal replicas based on the post-LLR and the external LLR; a replica selection unit (50) which selects a combination of transmission signal replicas from the transmission replicas according to the detection subject; a cancelation unit (35) which removes a received signal replica which is created based on the transmission signal replica combination which is selected from the received signals; and a MIMO separation unit (36) which carries out MIMO separation on the signal which has had the received signal replica removed.
When error correction decoding of a codeword in an error correction decoding portion (26) of a data reception device (2) fails, a MIMO processing portion (15) of a data transmission device (1) transforms and transmits a codeword which has been transmitted according to predetermined rules, and the error correction decoding portion (26) of the data reception device (2) uses the transformed codeword to play back data.
This transmission system (301) is provided with error correction encoding means (10) which converts an input data string to an encoded data string comprising an error correcting code and encoded data, data distribution means (20) which partitions an encoded data string from the error correction encoding means (10) into predetermined processing units in order to couple the same to a plurality of transmission paths (30), data coupling means (40) which couples signal strings from each of the transmission paths (30) in order to restore an encoded data string, error correction decoding means (50) which performs error correction and restoration on the encoded data string from the data coupling means (40) in order to output the input data string, and setting means (60) in which degree of redundancy at the error correction encoding means (10) and the number of partitions of the encoded data string at the data distribution means (20) are set.
A wireless communication system comprises a transmission device and a reception device, which are employed in transmitting a wireless signal comprising a plurality of sub-carriers, wherein the transmission device carries out an error correction coding of a data to be transmitted, zeroes a frequency of one or more sub-carriers, from among the plurality of sub-carriers that are employed in the transmission of a data that is obtained by error correction coding, thereby making the one or more sub-carriers thereof into null sub-carriers, transmits the data that is obtained by the error correction coding, and the reception device receives the plurality of sub-carrier signals from the transmission device, carries out an error correction decoding upon the signal thus received and obtains the data to be transmitted, and determines that interference is occurring upon the sub-carrier that employs the null sub-carrier when a reception power is detected upon the sub-carrier thereof that exceeds a preset baseline value.
