11. Fading Channels: Capacity and Channel Coding Rate in the Finite-Blocklength Regime
Sammanfattning : Information-theoretic studies on the fundamental limits of communication over wireless fading channels typically rely on simplifying assumptions, such as perfect channel state information (CSI), infinite blocklength, and vanishing probability of error. Although these assumptions are reasonable for most of the current wireless communication systems, they may be inaccurate for next-generation wireless systems. LÄS MER
12. Bounds on the maximum coding rate of multiple-access channels and feedback channels
Sammanfattning : We provide upper and lower bounds on the coding rate of multiple-access channels (MACs) and feedback channels.Traditional MACs have been extensively studied under the assumption of availability of perfect channel state information (CSI).In Paper A we relax this assumption for a Rayleigh block-fading MAC and provide bounds on the sum-rate capacity.

13. Voronoi Constellations for Coherent Fiber-Optic Communication Systems
Sammanfattning : The increasing demand for higher data rates is driving the adoption of high-spectral-efficiency (SE) transmission in communication systems. The well-known 1. LÄS MER
14. Capacity of MIMO Dispersive Fading Channels and the Achievable Error Performance of OFDM Signals in Frequency Dispersive Fading Channels
Sammanfattning : Communication over a single-input single-output (SISO) and a multiple-input multiple-output (MIMO) dispersive fading channel were studied in the context of the ergodic Shannon channel capacity and the achievable error performance. A major contribution to the study is the equivalent SISO and MIMO vector channel models, derived from the corresponding waveform channel models, using a complete orthonormal and finite set of eigenfunctions to represent the waveform channel's output.

15. Tools for the development of intensified perfusion processes for mammalian cell culture
Sammanfattning : Recombinant protein therapeutics have become an indispensable part of modern medicine to treat a wide variety of diseases. Their manufacture is mostly based on mammalian cells with fed-batch production bioreactors and downstream batch purification unit operations. LÄS MER
