Shannon introduced information theory in 1948. In Shannon’s model, the central question is to minimize the number of bits required to transmit a message from one party to another over a (possibly noisy) communication channel. Yao introduced communication complexity in 1979. In Yao’s model, the central question is to minimize the amount of communication required to compute a function of an input...

Purpose: The purpose of present research is to analyze theories proposed for social functions of communication media including public libraries. Also, it aims to explain and generalize a theory best coordinated with public libraries. In current analysis, public libraries have been explained regarding their position and functions as communication media. Methodology: Using meta-analysis method, ...

a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...

In this paper several computer simulations and pool experiments have been carried out to verify and demonstrate underwater communication between moving acoustic sensor nodes over different distances achieving optimum mutual information. We have developed GUI software “SAM-control” that generates m-sequences of 1023 length, handles their transmission and communications between sensor nodes. In a...

Molecular communication emerges as a promising communication paradigm for nanotechnology. However, solid mathematical foundations for information-theoretic analysis of molecular communication have not yet been built. In particular, no one has ever proven that the channel coding theorem applies to molecular communication, and no relationship between information rate capacity (maximum mutual info...

The brain – computer interface (BCI) provides a communicational channel between human and machine. Most of these systems are based on brain activities. Brain Computer-Interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. The success of this methodology depends on the selection of methods to process the brain signals in each pha...
