SYSTEMS AND METHODS FOR ASYNCHRONOUS RE-MODULATION WITH ADAPTIVE I/Q ADJUSTMENT
摘要
<p>Various embodiments provide for systems and methods for signal conversion of one modulated signal to another modulated signal using demodulation and then re-modulation. According to some embodiments, a signal receiving system may comprise an I/Q demodulator that demodulates a first modulated signal to an in-phase ("I") signal and a quadrature ("Q") signal, an I/Q signal adjuster that adaptively adjusts the Q signal to increase the signal-to-noise ratio (SNR) of a transitory signal that is based on a second modulated signal, and an I/Q modulator that modulates the I signal and the adjusted Q signal to the second modulated signal. To increase the SNR, the Q signal may be adjusted based on a calculated error determined for the transitory signal during demodulation by a demodulator downstream from the I/Q modulator.</p>
