通信原理基于Matlab的计算机仿真,书籍电子版和源代码完全版。 作 者：郭文彬 出 版 社：北京邮电大学出版社 出版日期：2006-6-1 内容简介 本书主要针对《通信原理》这门课程，通过实例详细讲解了利用Matlab进行信真的方法。书中给出了大量的Matlab脚文本文件和范例。通过计算机模拟与仿真，一方面能使读者加深对所学基本理论的理解；另一方面，使读者能迅速掌握Matlab进行通信系统仿真的技巧。 全书共10章，包括：Matlab基本知识、确定信号分析、随机过程、模拟调制、数字频带传输、模拟信号的数字化及编码、信道及信道容量、扩频通信与伪随机序列等内容。(Communication Theory full version of Matlab-based computer simulation, books, electronics, and source code. Adds Kuo: Press: Beijing University of Posts and Telecommunications Publishing Date :2006-6-1 Introduction book focused on " Communication Theory course through examples explain in detail the method of to using Matlab letter really. The book gives a lot of the Matlab the pin text file and example. Through computer modeling and simulation, which would enable readers to deepen the understanding of the basic theory On the other hand, so that readers can quickly grasp Matlab communication system simulation techniques. The book is 10 chapters, including: Matlab basic knowledge to determine the signal analysis, stochastic processes, analog modulation, digital band transmission, the analog signal is digitized and coding, channel and channel capacity, spread spectrum communication with pseudo-random sequences.)
