Document Type and Number:
Japanese Patent JP5535366
Kind Code:
B2
Abstract:
To reduce the process of a cell search including sector identification without increasing loads on a transmission/reception apparatus. A synchronization channel (SCH) included on downlink in a multicarrier mobile communication system is multiplied by a sector specific code and a cell specific code (step S1), assigned to subcarriers on the frequency axis (step S2), subjected to spreading processing and IFFT processing (steps S3, S4), and further subjected to insertion of GI and D/A conversion processing (steps S5, S6), and multicarrier is transmitted from a directional antenna of each sector (step S7). The receiving side specifies a SCH position by auto-correlation method or cross-correlation method, performs FFT, and then, concurrently performs identification of a sector by detection of the sector specific code, and acquisition of cell specific information by demodulation of the cell specific code.
