WIRE COMMUNICATION DEVICE, WIRE COMMUNICATION APPARATUS, WIRE COMMUNICATION METHOD, AND WIRE COMMUNICATION SYSTEM

摘要

A wire communication device (30) comprises a primary modulating section (32), a PN code generating section (34), a spread-modulating section (36), and a communication interface section (38). The primary modulating section (32) primary-modulates transmission data and generates a primary-modulated signal. The PN code generating section (34) generates a PN code in synchronism with a synchronizing signal having a predetermined period. The spread-modulating section (36) spread-modulates the primary-modulated signal according to the PN code and creates a spread-modulated signal. The communication interface section (38) sends the synchronizing signal and the spread-modulated signal in to a wire communication channel (3). Therefore a receiver can generate a spreading code for despread-demodulation according to the synchronizing signal received through the wire communication channel (3). As a result, when spectrum spreading is applied to a wire communication channel, a wire communication device for high-speed data communication, a wire communication apparatus, a wire communication method, and a wire communication system are provided.
