Fitts' law is a model of human psychomotor behavior developed in 1954 [6]. Extending Shannon’s theorem 17 in information theory (a formulation of effective information capacity of a communication channel), Fitts discovered a formal relationship that models speed/accuracy tradeoffs in rapid, aimed movement (not drawing or writing). According to Fitts’ Law, the time to move and point to a target ...

Firstly, an introduction of two-way communications channel is given. Then Shannon’s inner and outer bounds are introduced. Upon Shannon’s bounds, tighter lower and upper bounds are found for general discrete memoryless two-way channels. After that, the capacity regions of some specific two-way channels are discussed. Finally, a summary is given.

Active Systems with Uncertain Parameters: an Information-Theoretic Perspective by Gireeja Vishnu Ranade Doctor of Philosophy in Electrical Engineering and Computer Sciences University of California, Berkeley Professor Anant Sahai, Chair The sister fields of control and communication share many common goals. While communication aims to reduce uncertainty by communicating information about the st...

The problem of modelling channels is crucial for the efficient design of wireless systems [1, 2, 3]. The wireless channel suffers from constructive/destructive interference signaling [4, 5]. This yields a randomized channel with certain statistics to be discovered. Recently ([6, 7]), the need to increase spectral efficiency has motivated the use of multiple antennas at both the transmitter and ...

Shannon’s formula C = 2 log(1+P/N) is the emblematic expression for the information capacity of a communication channel. Hartley’s name is often associated with it, owing to Hartley’s rule: counting the highest possible number of distinguishable values for a given amplitude A and precision ±D yields a similar expression C0 = log(1+ A/D). In the information theory community, the following “histo...

Information theory concepts and methodologies constitute the background of how communication systems are studied and understood. They are focused mainly on the source-channel-receiver problem and on the asymptotic limits of accuracy and communication rates, which are the classical problems studied by Shannon. However, the impact of information theory on networks (acting as the channel) is just ...

Title of dissertation: ACHIEVABLE RATES, OPTIMAL SIGNALLING SCHEMES AND RESOURCE ALLOCATION FOR FADING WIRELESS CHANNELS Onur Kaya, Doctor of Philosophy, 2005 Dissertation directed by: Professor Şennur Ulukuş Department of Electrical and Computer Engineering The proliferation of services involving the transmission of high rate data traffic over wireless channels makes it essential to overcome t...

The year 1948 saw the publication of Andre Weil’s monograph Sur les Courves Algebriques et les Variétés qui s’en Deduisent and of Claude Shannon’s work on The mathematical theory of communication. The first gave the details of Weil’s celebrated proof of the Riemann Hypothesis for algebraic curves over finite fields, while the second lay down the foundations for information theory, including the...

OFDM is a promising technique for high data rate transmission and the channel estimation is very important for implementation of OFDM. In this paper, cyclic prefix (CP) can be used as a source of channel information which is originally used to reduce inter symbol interference (ISI). Based on this CP observation, we propose two cross coupled dual Kalman filters to track the channel variations wi...

In a multistatic cloud radar system, receive elements (REs) measure signals sent by a transmit element (TE) and reflected from a target and possibly clutter, in the presence of interference and noise. The REs communicate over non-ideal backhaul links with a fusion center (FC), or cloud processor, where the presence or absence of the target is determined. Two different backhaul architectures are...
