Abstract

A signal design method for the uplink in the cellular mobile CDMA systems is proposed. The proposed method uses binary complete complementary code as comb-spectrum pseudo-periodic sequences. The designed signals are without co-channel interference nor influence of multipath fading, when the system is synchronized approximately. Any approximation of synchronization is acceptable by arranging the signal design. In order to avoid the inter-cell interference using different complete complementary codes, we discuss the characteristics of the correlations between different complete complementary codes
