ABSTRACT:
A wireless communication system performs wireless transmitting and receiving of data between first and second communication devices. The device transmits from the first communication device to the second communication device a prescribed signal by a prescribed carrier signal having a prescribed carrier frequency. The prescribed signal transmitted from the first communication device is received in the second communication device. The device generates in the second communication device a signal of prescribed frequency which is phase synchronous with the prescribed carrier signal. Transmission data is spread spectrum modulated using the signal of prescribed frequency generated in the generating step. The spread spectrum modulated signal is transmitted from the second communication device to the first communication device. The first communication device receives the spread spectrum modulated signal transmitted from the second communication device.
