Multi-Antenna Channel Reconstruction for Spatial Modulation

The patent applies parameter changes by transforming the physical channel parameters through reconstruction techniques. Specifically, it modifies the channel matrix parameters to create virtual channels with reduced correlation, while the actual physical channels remain unchanged. This allows the system to achieve low correlation performance without changing the physical antenna configuration.

The patent introduces an intermediary channel reconstruction process between the physical channel and the spatial modulation detection. By inserting this intermediate layer that creates virtual channel representations, the system can achieve low correlation without directly modifying the physical antenna setup or the detection process.

The patent creates virtual copies of the physical channels through reconstruction techniques. Instead of using multiple physical radio frequency links, it generates multiple virtual channel representations that can be processed independently, reducing hardware complexity while maintaining capacity benefits.

The patent replaces the mechanical/physical approach of using multiple independent radio frequency links with a signal processing approach. By substituting physical hardware complexity with computational channel reconstruction, the system achieves similar capacity gains with reduced hardware requirements.
