摘要： To provide a system that can accommodate a greater number of terminals within a limited band and can obtain a higher transmission rate. While the number of frequency signals (spectrums) output in parallel by performing a spread spectrum from the DFT unit of each terminal is 12, the number of sub-carriers constituting one sub-channel is set at 10 or 11. In this case, the users (users A and G) allocated to the sub-channels at both ends of the band will not perform transmission of one frequency signal at the end (one sub-carrier) of all the frequency signals output from the DFT unit, whereas the users (users B to F) allocated to the other sub-channels will not perform transmission of the frequency signals at the ends (two sub-carriers). This transmission can be realized by deleting (clipping) the associated number of signals from both ends or from one end of the frequency signals output from the DFT unit of each terminal and allocating the frequency signals after clipping, to individual sub-channels.

摘要： By controlling to select encoding appropriately considering characteristics of equalization and decoding of a receiving apparatus employing a turbo equalization technology, it is possible to attain a high transmission characteristic. Information bits of two systems including a sequence which is input to a first RSC encoding unit 22 and a sequence which is input through an interleaving unit 21 to a second RSC encoding unit 23 are set for input information bits, and each of which is subjected to RSC encoding. Each encoded parity bit is input to a puncturing unit 24. Since a systematic bit obtained by the first RSC encoding unit 22 is the information bit itself, a systematic bit obtained by the second RSC encoding unit 23 is not transmitted. In the puncturing unit 24, while puncturing is applied according to a predetermined coding rate, selection of either an RSC code or a turbo code is carried out by a puncturing control unit 25.

摘要： A wireless communication system includes a first communication device which arranges a frequency signal into which a single carrier signal is converted by time-to-frequency conversion in subcarriers and wirelessly transmits a resultant signal and a second communication device which receives the signal wirelessly transmitted by the first communication device. The wireless communication system includes a selection unit which calculates, for each determined selection candidate as a combination of a predetermined segment size and information indicating predetermined average transmission power, a value indicating reception quality in the second communication device upon transmission by the first communication device by using an arrangement using the predetermined segment size, and the predetermined average transmission power, and which selects a selection candidate to be used upon transmission by the first communication device from among the selection candidates based on the calculated value indicating the reception quality. Therefore, an excellent transmission efficiency is obtained.
