Signal Fidelity in Degenerate and Nondegenerate Mode Parametric Amplifier Receiving Antennas
<|reference_start|>Signal Fidelity in Degenerate and Nondegenerate Mode Parametric Amplifier Receiving Antennas: The gain, received power bandwidth, transient characteristics, and signal fidelity of two time-varying electrically small antennas based on parametric amplifier design are studied using practical QAM signals. Results show that interference from the difference harmonic present in the response of degenerate-mode parametric amplification decreases its signal throughput relative to a reference linear time-invariant (LTI) receiver, despite its apparent increased received power bandwidth in the frequency domain. The analysis also demonstrates that a non-degenerate parametric receiver, lacking this detrimental effect, exhibits increased signal throughput over the reference LTI receiver.<|reference_end|>
