Digital Communications I: Modulation and Coding Course

This course is about a communication system which is used to transfer information from a source to a destination. Examples of communication systems are telephones, wireless data access, television and many others.How to transmit the information from a source to a destination. How to evaluate the quality of the received information. What kinds of design goals to consider for a specific application. How to trade-off between various parameters (such as bandwidth and power) due to the design limitations and goals. How to analyze a digital communication system link to achieve an overall system insight | Digital communications I Modulation and Coding Course B------- ------ -------B Period 3 - 2007 Catharina Logothetis Lecture 6 Last time we talked about Signal detection in AWGN channels Minimum distance detector Maximum likelihood Average probability of symbol error Union bound on error probability Upper bound on error probability based on the minimum distance Lecture 6 2 Today we are going to talk about Another source of error Inter-symbol interference ISI Nyquist theorem The techniques to reduce ISI Pulse shaping Equalization Lecture 6
