This book is an introduction to information and coding theory at the graduate or advanced undergraduate level. It assumes a basic knowledge of probability and modern algebra, but is otherwise self- contained. The intent is to describe as clearly as possible the fundamental issues involved in these...
Information theoryChapter 5 uses the widely observed dichotomy between routine and non-routine behavior to explain how an entity with bounded rationality can achieve error-free behavior. Error-free communication and perfect control were shown to be duals. In terms of the simplified model of Chapter ...

Historians may perhaps come to refer to it as the century of information, just as its predecessor is associated with the process of industrialisation. Successive technological developments such as the telephone, radio, television, computers and the Internet have had profound effects on the way we ...

当信源各符号出现概率相等时,信源具有最大熵。 熵的范围为: 在编码中用熵值衡量是否为最佳编码。若以 表示编码器输出码字的平均码长,则当 >> :有冗余,不是最佳编码; < :不可能; :最佳编码( 稍大于 )。 无损编码定理 离散信源X无损编码所能达到的最小速率不能低于该信源的信源熵,即: 信源编码定理(有损编...
