<p><P>PROBLEM TO BE SOLVED: To provide a transmitter capable of eliminating local leakage regardless of changes in the state of modulation by reducing an effect on modulation signals. <P>SOLUTION: The modulating device comprises a signal generator 13 for generating first and second data, a local oscillating means 10 that generates a first local signal and a second local signal in the phase opposite to the first local signal, a first modulator 1 that generates modulation waves from the first data and the first local signal, a second modulator 2 that generates modulation waves from the second data and the second local signal, and a synthesizer 3 that synthesizes modulation waves generated by the first and second modulators 1 and 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
