Receiver structure - Impact of AWGN and ISI on the transmitted signal - Optimum filter to maximize SNR - Matched filter and correlator receiver | Digital Communications I Modulation and Coding Course B------ ------- -------B Period 3 - 2007 Catharina Logothetis Lecture 5 Last time we talked about Receiver structure Impact of AWGN and ISI on the transmitted signal Optimum filter to maximize SNR Matched filter and correlator receiver Signal space used for detection Orthogonal N-dimensional space Signal to waveform transformation and vice versa Lecture 5 2 Today we are going to talk 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 5
