Context-aware lossless and lossy compression of radio frequency signals

A Martí, J Portell, J Riba, O Mas - Sensors, 2023 - mdpi.com
We propose an algorithm based on linear prediction that can perform both the lossless and
near-lossless compression of RF signals. The proposed algorithm is coupled with two signal …
