Being the radio communication base station device which transmits the multi carrier signal which consists of the radio communication base station device, the radio communication mobile station device

摘要

At the time of multiple carrier communicating, the number or cell number of sectors increasing, preventing the deterioration of orthogonality between the pilot signal series in between the contiguity sector due to frequency selective fading or between the contiguity cells the radio communication device which can improve reception quality. In this device, the irregularity section (102-1 - 102-m), modulating the data after the encoding, it forms data symbol, the pilot symbol formation department (103), modulating the pilot signal series which is input, it forms pilot symbol, the multiplex section (104), time multiple does pilot symbol and data symbol. In addition, as pilot signal series among the plural OVSF series where serial length equality crosses mutually mutually making use of OVSF series, in the contiguity sector the other OVSF series which crosses at the unit which is shorter than that serial length vis-a-vis the OVSF series which is used as pilot signal series is input the pilot symbol formation department (103).
