Dither and data compression

IEEE Transactions on Signal Processing, 1997
This correspondence presents entropy analyses for dithered and undithered quantized sources. Two methods are discussed that reduce the increase in entropy caused by the dither. The first method supplies the dither to the lossless encoding-decoding scheme. It is argued that this increases the complexity of the encoding-decoding scheme.

Orthogonal waveform separation based on echo compression for airborne MIMO-SAR systems

The Journal of Engineering, 2019
Attention has been devoted to multi-input multi-output (MIMO) synthetic aperture radar (SAR) systems in recent years. The applications of MIMO-SAR systems which involve high-resolution wide-swath remote sensing, three-dimensional imaging, and multi ...

Variational Autoencoders for Network Lifetime Enhancement in Wireless Sensors

Sensors
Wireless sensor networks (WSNs) are structured for monitoring an area with distributed sensors and built-in batteries. However, most of their battery energy is consumed during the data transmission process.

The Amount of Data Required to Recognize a Writer’s Style Is Consistent Across Different Languages of the World

Entropy
In this paper, we apply an information-theoretic method proposed by Ryabko and Savina (therefore called the RS-method), based on the use of data compression, to recognize the individual author’s style of a writer across four languages from different ...
