Mobile communications device, communications system, and communications method

摘要

The device uses a chip clock signal (34) and an antenna radio circuit for receiving and sending information. A spreading code is generated (35) on the basis of the chip clock signal. A signal is despreaded receivedby the antenna radio circiot. A correlation output circuit extracts a correlation output from the despread signal and spreads a transmission signal on the basis of the spreading code. Independent claims describe a mobile communication device and a communication system.
