Capacity analysis for continuous-alphabet channels with side information, part I: a general framework
TL;DR: This two-part paper derives necessary and sufficient conditions that characterize the capacity value and the capacity-achieving measure for continuous-alphabet channels with side information at the receiver and establishes novel necessary andsufficient conditions for weak* continuity and strict concavity of the mutual information.

System and method for canceling acoustic echoes in audio-conference communication systems
TL;DR: In this article, an acoustic echo canceller (812) is integrated into the frequency-domain coder/decoder (802) and ameliorates or removes acoustic echoes from audio signals that have been transformed to the frequency domain and divided into subbands by the frequencydomain Coder/Decoder(802).
Book
DSP First
TL;DR: The "DSP First" approach introduces the use of mathematics as the language for thinking about engineering problems, lays the groundwork for subsequent courses, and gives students hands-on experiences with MATLAB.

Multi-media and World Wide Web resources for teaching DSP
TL;DR: A new digital signal processing (DSP) course designed to build students intuition about signals and systems is presented, making extensive use of multi-media demonstrations to relate real-world signals and discrete-time systems to their mathematical descriptions.
