To Compress or Not to Compress: Revisiting the Use of Chest Compressions in LVAD Patients

To compress or not to compress ?

| For practical communications which transmit nite blocks of source data over noisy channels, we question the common practice to compress (C) the source and then to add redundancy for error control. Rather we exploit the redundancy of the non-compressed source (NC) at the channel decoder by source-controlled channel decoding. For a simple binary Markov source and a Rayleigh fading channel we si...

To Compress or Not To Compress: Processing vs Transmission Tradeoffs for Energy Constrained Sensor Networking

In the past few years, lossy compression has been widely applied in the field of wireless sensor networks (WSN), where energy efficiency is a crucial concern due to the constrained nature of the transmission devices. Often, the common thinking among researchers and implementers is that compression is always a good choice, because the major source of energy consumption in a sensor node comes fro...

To Use the Codebook Information or Not: A Study of the Compress-and-Forward Relay Strategy

The motivation of this thesis is to understand how nodes can cooperate in a particular relay channel, say a relay channel with orthogonal link between relay and destination. We are especially interested in the scenario where relay cannot decode the message sent because the coding rate is too large vis-a-vis what it can handle, and try to investigate the optimality of compress-and-forward strate...

How to Compress Asymmetric Communication

We study the relationship between communication and information in 2-party communication protocols when the information is asymmetric. If I denotes the number of bits of information revealed by the first party, I denotes the information revealed by the second party, and C is the number of bits of communication in the protocol, we show that one can simulate the protocol using order I + 4 √ C3 · ...
