【簡介】 Promotes problem-solving and critical-thinking skills through the use of MATLAB as a "virtual laboratory" and challenges readers to understand and apply these techniques on their own. Presents a basic background of signals and systems. Covers the performances of analog modulation and demodulation techniques in the presence and absence of additive noise. Companion website includes all the MATLAB and Simulink files used in the text with numerous comments added to most files to make them easier to understand. New to this edition ‧New chapter: Multicarrier Modulation and OFDM. ‧New chapter: Multiple Antenna Systems. ‧New chapter: Digital Transmission Through Wireless Channels. ‧New examples with additional practical real-life engineering problems now included. ‧New sections on DPCM, ADPCM, and DM; turbo codes and decoding; LDPC codes and decoding. ‧Compliant with the latest version of MATLAB. ‧Augmented coverage of Random Processes. ‧Revised and updated Simulink supplement with tutorial problems available online. 【目錄】 1.
