The method includes a block cycle determination step in which the distribution of a block cycle constructed from non-zero cyclic shift element values is determined for the basic matrix of the LDPC code, a priority determination step in which the priorities of the non-zero cyclic shift element values included in each block cycle are determined on the basis of the determined block cycle distribution, and a calculation step in which the greatest common divisor is determined for the permutation elements of all magnitudes in the check matrix of the LDPC code, and the divisor is factored. According to this method, short cycles will not be included in any actual check matrix of an LDPC code constructed by using all different permutation elements.

摘要： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.

摘要： A wireless communication apparatus and a wireless communication method wherein even when the permissible delay amount of data is small, the permissible delay thereof can be satisfied. A data type determining part (101) determines whether the delay of transport data or control information should be allowed or not. A pilot signal insertion control part (102) decides, based on pilot insertion interval information and allowable delay information, that a pilot signal is placed adjacently to data that is not allowed to delay. A multiplexing part (106) multiplexes encoded and modulated transport data with the pilot signal generated by a pilot signal generating part (105) in such a manner that realizes the placement decided by the pilot signal insertion control part (102).
