摘要： 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.

摘要： [Problems] To reduce a cell search process including sector identification without increasing a load on a transmission/reception device.[Means for Solving Problems] A synchronization channel (SCH) contained in a down link of a multi-carrier mobile communication system is multiplied by a sector unique code and a cell unique code (step S1). The multiplication result is allocated to a sub-carrier on the frequency axis (step S2) and subjected to a spread process and an IFFT process (steps S3, S4). Furthermore, GI is inserted and D/A conversion are performed (steps S5, S6). A multi-carrier is transmitted from a directivity antenna of each sector (step S7). A reception side identifies the SCH position by the self-correlation method or the mutual correlation method and performs the FFT. After this, the reception side simultaneously performs identification of a sector by detecting a sector unique code and acquisition of cell unique information by demodulating a cell unique code.
