CDMA COMMUNICATION DEVICE

摘要

A CDMA communication device for multi-code transmission in a communication system in which code division multiple access (CDMA) is adopted. A spreading section (4) spreads a predetermined transmission data sequence into data on chip rate by using spreading codes orthogonal to one another. A segment interleave section (5) segments data corresponding to one symbol after the spreading into segments having a segment size corresponding to the number of chips at which the spreading codes hold their orthogonality so as to conduct interleave for each segment.
