Lossless Wideband RF Compression via Lifting-Based IIR Subband Decomposition
Charles Cooper, Michael W. Marcellin · IEEE Transactions on Aerospace and Electronic Systems · 2019
This correspondence presents a scheme for the lossless compression of wideband spectrally and/or temporally sparse radio-frequency intercepts. It decomposes intercepts into time/frequency partitions using an adaptive invertible channelizer based on infinite impulse response orthogonal wavelet filter banks. The resulting subband decomposition is compressed via arithmetic coding.
