现代通信系统(MATLAB版)(第二版)刘树棠译 本书系Brooks/Cole出版公司（Thomson Learning出版集团的下属子公司）2000年推出的BookWare系列丛书（BookWare Companion SeriseTM）之一种。该书提供了利用MATLAB的普及型学生版本在计算机上解决“现代通信系统”这门课程中涉及的几乎所有方面的问题的分析思路、方法、MATLAB脚本文件和处理结果的范例以及供学生自主学习研讨的习题。全书内容分为9章，分别是：信号与线性系统；随机过程；模拟调制；模拟/数字转换；基带数字传输；带限信道的数字传输；载波调制的数字传输；信道容量和编码；扩频通信系统。 (This book Brooks/Cole Publishing (Thomson Learning Publishing Group, a subsidiary) in 2000 launched BookWare Series (BookWare Companion SeriseTM) of a kind. The book provides the advantage of the popularity-based student version of MATLAB on the computer to solve the " modern communications systems," This course covered almost all aspects of the analysis of ideas, methods, MATLAB script files and processing the results of examples, as well as independent study for students seminar to answer. The book consists of nine chapters, namely: Signal and Linear System stochastic process analog modulation analog/digital conversion base-band digital transmission band-limited channel digital transmission carrier modulation digital transmission channel capacity and coding spread-spectrum communication systems.)
