# The Mathematical Theory of Communication

HE recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. A basis for such a theory is contained in the important papers of Nyquist1 and Hartley2 on this subject. In the present paper we will extend the theory to include a number of new factors, in particular the effect of noise in the channel, and the savings possible due to the statistical structure of the…

INFORMATION THEORY AND CODING

The mathematical foundation of Information Measure or Shannon’s Entropy is discussed and an application of this entropy in coding theory is also discussed showing that how much data can be compressed.

SOME REMARKS ON THE CAPACITY OF A COMMUNICATION CHANNEL

- Mathematics
- 1960

In Section I an interpretation of the capacity theorem is given by introduing the cost consideration into the information system and a close connection between them will be shown by presenting a general theorem which includes the two theorems as the two special cases.

Shannon theory. Myths and reality

- Computer Science

The author claims that the lower bound of signal reception is no longer a constant value, ln(2), but depends on many factors such, as the ratio of bandwidth-to-information transmission rate, the class of a receiver, the kind of reception system, and – of course – on the characteristics of noise, including entropy.

A channel hopping technique I: theoretical studies on band efficiency and capacity

- Business, Computer Science2004 International Conference on Communications, Circuits and Systems (IEEE Cat. No.04EX914)
- 2004

The theoretical analysis shows that the capacity gain of the channel hopping technique is the same as that of transmit diversity over the "flat" channel, however, for a DS-CDMA system under the assumption that the multiuser interference obeys a Gaussian distribution, the proposed system has larger system capacity.

The influence of delay upon an idealized channel's bandwidth

An optimization problem in calculating the bandwidth of a covert timing channel is discussed. In particular, the question of how dependent the bandwidth is on the magnitude of the modulation is…

Channel State Quantization in MIMO Broadcast Systems: Architectures and Codes

- Computer Science
- 2010

New design principles for channel feedback design in multi-user multipleantenna broadcast system design are developed and shown that the system designer is afforded extra degrees of freedom in the choice of the channel quantizer due to the multi- user diversity of the system.
