Abstract: Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.

Abstract: An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.

Abstract: A multicarrier transmitting apparatus capable of improving the data symbol error rate characteristic to improve the reception quality. In this apparatus, a replacement position deciding part (141) decides, based on a number of replacements notified of by a scheduler (110), which one of a plurality of data symbols should replaced by a second pilot. Herein, a restricted condition, which is ‘RF after replacement is equal to or greater than RF before replacement minus one’, is satisfied.

Abstract: A GI insertion section 105 inserts a guard interval into transmission data. Delay addition sections 107-1, 107-2 set a delay time in the transmission data. An arrival time calculation section 115 calculates for each directivity an arrival time after data is transmitted from the other party of communication until the data is received from received data of each directivity. A delay time determining section 116 calculates a difference in the arrival time between transmission data transmitted with two directivities and sets the calculated arrival time difference in the transmission data to be transmitted with the directivity corresponding to the smaller arrival time as a delay time. A GI length determining section 117 sets a minimum arrival time of the calculated arrival times as a guard interval. This allows a transmission rate to be improved by shortening the length of a guard interval in a radio communication system to which a system of transmitting an OFDM signal with a directivity is applied.

Abstract: A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.
