Course Aims This course aims: to introduce the theory and systems engineering of modern digital communications,and to enhance understanding of communication systems protocols. UESTC-Introduction Prof李晓峰 3

Intended Learning Outcomes By the end of this course students will be able to: state features and advantages of digital communication; describe common forms of digital communication,including radio and wire transmission; explain typical forms of modulation,such as amplitude,phase and frequency-shift keying and interpret their waveforms; compare the attributes and performances of different forms of modulation; develop the structures for optimal receivers and describe the impact of nonoptimality; design an appropriate transmission method for a given type of signal; understand modem wireless schemes,such as OFDM and spread spectrum UESTC-Introduction Prof李晓峰 4
