- Split the 80Mhz into 8 channels of 10Mhz each
- Each channel consists of 2048 freq points
- Input: [8x2048]
Architecture
- 1D multi-channel CNN
- FC Layers
- Softmax

ORACLE: Optimized Radio clAssification through Convolutional neuraL nEtworks

-
Cons
- Its too sensitive, able to fingerprint different devices even if identical make/model
- Performs badly in channel variant env
- A pretrained model based on data collected in Time A and Location A, will not work in Time B... or Location B... due to IQ data dependance on environment which varies in time and space.
-
Considerations
- HIgher quality SDR produces less impairments and make it less discrimitative for IQ data
- The same signal received over different channels actually can become 'different'. So channel variance can be a problem.
