Description Scientific calculator. Allows to perform caclulation with high precicion and implements most populatr MATHEMATICAL functions: sin, cos, tan, asin, acon, atan, exp, log, sqr, floor and ceil. Also it make it possible to define your own function, store results in variables and use variable sin expressions. Calculator store al formuls you have entered. Plot function can be used to draw graph of function with single argument. More detailed description of calculator is here.

as a message came into prominence with the publication in 1948 of an influential paper by Claude Shannon, "A MATHEMATICAL Theory of Communication." This paper provides the foundations of information theory and endows the word information not only with a technical meaning but also a measure. If the sending device is equally likely to send any one of a set of N messages, then the preferred measure of "the information produced when one message is chosen from the set" is the base two logarithm of N (This measure is called self-information). In this paper, Shannon cont

《A MATHEMATICAL theory of communication》，Shannon信息论的开山之作，此文可以看作是现代通信的理论基础。文中提出熵作为信息的度量，个人认为仍是不可替代的。在量子信息中提出的量子信息熵，可以看作是一种模仿。学理工科的人都应该好好学习看看。当然，同时期的苏联科学家从数学的角度（概率论）给出了几乎一模一样的结果。只是过程更加抽象与严谨。

The field of digital communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., digital subscriber loop, cable, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the MATHEMATICAL background necessary to understand communication theory.

In general there are three different techniques for performance evaluation of systems and networks: MATHEMATICAL analysis, measurements, and computer simulation. All these techniques have their strength and weaknesses. In the literature there are plenty of discussions about when to use which technique, how to apply it, and which pitfalls are related to which evaluation technique.

Before delving into the details of orthogonal frequency division multiplexing (OFDM), relevant background material must be presented first. The purpose of this chapter is to provide the necessary building blocks for the development of OFDM principles. Included in this chapter are reviews of stochastic and random process, discrete-time signals and systems, and the Discrete Fourier Transform (DFT). Tooled with the necessary MATHEMATICAL foundation, we proceed with an overview of digital communication systems and OFDM communication systems. We conclude the chapter with summaries of the OFDM wireless LAN standards currently in existence and a high-level comparison of single carrier systems versus OFDM.

The purpose of this book is to introduce the concept of the Multiple Input Multiple Output (MIMO) radio channel, which is an intelligent communication method based upon using multiple antennas. The book opens by explaining MIMO in layman’s terms to help stu- dents and people in industry working in related areas become easily familiarised with the concept. Therefore the structure of the book will be carefully arranged to allow a user to progress steadily through the chapters and understand the fundamental and MATHEMATICAL principles behind MIMO through the visual and explanatory way in which they will be written. It is the intention that several references will also be provided, leading to further reading in this highly researched technology.
