Articles
- AM vs FM Modulation (Jodi and Eric)
- Single Side Band (SSB) Modulation (Nick Christman, in progress)
- Double Side Band (DSB) Modulation (Joshua Sarris)
Links
- PSK31 Links
- Jeff McDow's Senior Report on Morse Code Detection
- Matched Filter A Posteriori Detector Paper
- The sauditor program patched for fftw3.
- Audacity file for testing with your CW Decoder Project
- Jack Audio Connection Kit Manual
- Demorse
- Using a Pipe or Fifo
- More on Pipes and other C Functions
- Free Open Textbook on Communications Systems
- Shannon's Papers On Information Theory
- Communications in the Presence of Noise, Proceedings of the IRE, January, 1949 This paper derives and explains Shannon's most important results. It is very understandable for someone who has taken Signals and Systems.
- Shannon's Bell Labs Technical Journal Articles 1948. These are more detailed.
