Multi-carrier transmission/reception apparatus |
摘要 |
A multicarrier radio communication technology that enables radio resources to be used effectively, interference-to be suppressed, and a cell search to be performed at high speed, in a multicarrier CDMA system. In this technology, a secondary synchronization code (S-SCH signal) for identifying the group of scrambling codes divided into groups beforehand is frequency multiplexed in a plurality of subcarriers. A secondary synchronization code is coded in the time direction. Subcarriers in which a secondary synchronization code is multiplexed are mutually separated and equally spaced. The number of subcarriers in which a secondary synchronization code is multiplexed can be set to a small value with respect to the total number of subcarriers. A secondary synchronization code is an orthogonal code. On the receiving side, a cell search is carried out using such a frequency multiplexed type S-SCH.
