Title: Modulator, transmitter, and computer program
Inventor: NOHARA MANABU
IPC: H04B10/54
Filed: 2002-09-18
Abstract: <P>PROBLEM TO BE SOLVED: To provide a modulator capable of setting a frequency for performing a high speed data communication without distortions by using an optical device having nonlinear factors.  <P>SOLUTION: Modulation waves are generated by modulating data transmitted by a prescribed modulation system. Optical data communication is performed by transmitting optical modulation waves by driving the optical device by the modulation waves. Cross modulation waves are generated in the modulation of the data transmitted since the optical device has the nonlinear factors. The problem of the cross modulation waves is eliminated by selecting a carrier frequency so as to prevent the cross modulation waves from intruding into a band to be used for the transmission of the data to be transmitted. As a result, the data transmission without distortions can be obtained. Reduction in costs can be achieved by using an LED or the like as the optical device. Also, the high speed data transmission can be achieved by using a multi-value modulation system.  <P>COPYRIGHT: (C)2004,JPO
