Title:

COMMUNICATION SYSTEM EMPLOYING CROSS-CORRELATION SUPPRESSION TYPE SPREAD SYSTEM SET

Document Type and Number:

Japanese Patent JP2003023675

Kind Code:

A

Abstract:

To provide a cross-correlation suppression type spread system set with a low power bandwidth product that enhances a frequency utilization efficiency so as to suppress not only an in-sector or in-cell interference noise but also an inter-sector or inter-cell interference noise and to provide a CDMA(code division multiple access) communication system employing the cross-correlation suppression type spread system set.

A system belonging to one set of cross-correlation system is assigned to the system for pilot transmission of each user belonging to an adjacent sector or cell and to a data transmission spread system used by each sector or cell without causing duplication.
