Testing Optimality of Sequential Decision-Making
Meik Dörpinghaus, Izaak Neri, Édgar Roldán +2
This paper provides a statistical method to test whether a system that performs a binary sequential hypothesis test is optimal in the sense of minimizing the average decision times…
An Information Theoretic Analysis of Sequential Decision-Making
Meik Dörpinghaus, Édgar Roldán, Izaak Neri +2
We provide a novel analysis of Wald's sequential probability ratio test based on information theoretic measures for symmetric thresholds, symmetric noise, and equally likely hypoth…
Decision Making in the Arrow of Time
Édgar Roldán, Izaak Neri, Meik Dörpinghaus +2
We show that the steady-state entropy production rate of a stochastic process is inversely proportional to the minimal time needed to decide on the direction of the arrow of time.…
Oversampling Increases the Pre-Log of Noncoherent Rayleigh Fading Channels
Meik Dörpinghaus, Günther Koliander, Giuseppe Durisi +2
We analyze the capacity of a continuous-time, time-selective, Rayleigh block-fading channel in the high signal-to-noise ratio (SNR) regime. The fading process is assumed stationary…
On the Achievable Rate of Stationary Rayleigh Flat-Fading Channels with Gaussian Inputs
Meik Dörpinghaus, Heinrich Meyr
In this work, we consider a discrete-time stationary Rayleigh flat-fading channel with unknown channel state information at transmitter and receiver. The law of the channel is pres…
On the Gain of Joint Processing of Pilot and Data Symbols in Stationary Rayleigh Fading Channels
Meik Dörpinghaus, Adrian Ispas, Heinrich Meyr
In many typical mobile communication receivers the channel is estimated based on pilot symbols to allow for a coherent detection and decoding in a separate processing step. Current…
On Complexity, Energy- and Implementation-Efficiency of Channel Decoders
Frank Kienle, Norbert Wehn, Heinrich Meyr
Future wireless communication systems require efficient and flexible baseband receivers. Meaningful efficiency metrics are key for design space exploration to quantify the algorith…
A Scalable VLSI Architecture for Soft-Input Soft-Output Depth-First Sphere Decoding
Ernst Martin Witte, Filippo Borlenghi, Gerd Ascheid +2
Multiple-input multiple-output (MIMO) wireless transmission imposes huge challenges on the design of efficient hardware architectures for iterative receivers. A major challenge is…
Efficient And Portable SDR Waveform Development: The Nucleus Concept
Venkatesh Ramakrishnan, Ernst M. Witte, Torsten Kempf +5
Future wireless communication systems should be flexible to support different waveforms (WFs) and be cognitive to sense the environment and tune themselves. This has lead to tremen…
