基本説明
最先端の通信システムの基礎理論と原理を詳述するベストセラーテキスト。
Throughout, Haykin emphasizes the statistical underpinnings of communication theory in a complete and detailed manner. Readers are guided though topics ranging from pulse modulation and passband digital transmission to random processes and error-control coding. The fifth edition has also been revised to include an extensive treatment of digital communications.
Full Description
This best-selling, easy-to-read, communication systems text continues to include the most comprehensive coverage of digital communications in an undergraduate level text in this fourth edition. In addition to being the most up-to-date communications text available, Simon Haykin has added more MATLAB computer experiments and improved examples and problems throughout. Intended for use in the Communication Systems course in the Electrical Engineering core curriculum. This course is typically offered at the junior/senior level in electrical engineering departments at the majority of four year colleges and universities that have electrical engineering programs. The introductory course in communication systems is required for electrical engineering majors. This text will also appeal to a small segment of the professional engineering market.
