Inhalt:
We propose a fading-free δ-σ modulation scheme based on Alamouti coding to overcome dispersion-induced power fading obstacle, and generate dual-band signals at both sub-6GHz and millimeter-wave without up-conversion. We demonstrate high-fidelity transmission of 1048576-/262144-QAM signals at 25-/30-GHz carrier frequencies over 25-/10-km SSMF with direct detection.
