UP-CONVERSION BASED ON GATED INFORMATION SIGNAL |
摘要 |
A method and system is described wherein an information signal is gated at a frequency that is a sub-harmonic of the frequency of the desired output signal. In the modulation embodiments, the information signal is modulated as part of the up-conversion process. In a first modulation embodiment, one information signal is phase modulated onto the carrier signal as part of the up-conversion process. In a second modulation embodiment, two information signals are multiplied, and, as part of the up-conversion process, one signal is phase modulated onto the carrier and the other signal is amplitude modulated onto the carrier. In a third modulation embodiment, one information signal is phase modulated onto the "I" phase of the carrier signal as part of the up-conversion process and a second information signal is phase modulated onto the "Q" phase of the carrier as part of the up-conversion process.
