## Core Methodology

### Architecture: EMRFormer
End-to-end spiking neural network applying spike-driven transformer to automatic modulation recognition (AMR) under neuromorphic hardware constraints.

### Key Components
1. **Adaptive Spike Encoder**: Converts raw IQ waveforms into spike representations while preserving temporal information
2. **Integer Leaky Integrate-and-Fire (I-LIF) Neurons**: Mitigates effective information degradation in spike encoding
3. **Spike-Separable CNN (SSCNN)**: Multi-scale temporal feature extraction from raw IQ data
4. **SpikeFormer Integration**: Spike-driven transformer backbone combining SSCNN with temporal attention

### Innovation Points
- First application of spike-driven transformers to AMR tasks
- Integer LIF neurons enable hardware-friendly computation
- End-to-end pipeline from raw IQ waveforms to modulation classification
- Deployed and validated on KA200 neuromorphic chip

### Results
- **Accuracy**: SOTA across multiple modulation datasets, outperforming all baselines
- **Low SNR Robustness**: Maintains strong performance in challenging signal conditions
- **Energy Efficiency**: 90%+ theoretical energy reduction vs ANN counterparts
- **Hardware Deployment**: 5x power reduction on KA200 vs 3090 GPU or Orin NX
