Systems and methods for asynchronous re-modulation with adaptive i/q adjustment

A signal receiving system configured to process a transitory signal, the signal receiving system comprising:

• a downstream demodulator configured to demodulate the transitory signal and provide a mean squared error (MSE) of the transitory signal;
• an algorithm module configured to determine a calculated error for the transitory signal based on the MSE;
• and
• a telemetry module configured to transmit the calculated error to an I/Q signal adjustor, the I/Q signal adjustor being configured to adaptively adjust an in-phase (“I”) signal or a quadrature (“Q”) signal to increase a signal-to-noise ratio (SNR) of the transitory signal that is based on the calculated error, and the transitory signal being based on the I signal and the Q signal as adjusted.

A method for downconverting a first modulated signal to a second modulated signal, the method comprising:

• demodulating the first modulated signal to an in-phase (“I”) signal and a quadrature (“Q”) signal based on a first oscillator signal, the first modulated signal being modulated based on a second oscillator signal that is asynchronous to the first oscillator signal;
• adaptively adjusting the Q signal to increase a signal-to-noise ratio (SNR) for a transitory signal that is based on the second modulated signal, the Q signal being adjusted based on a calculated error for the transitory signal;
• and
• modulating the second modulated signal based on the I signal and the Q signal as adjusted.
