Again, Again! Why do some modes work better?
Location N/ALecture Summary
Ever wonder why CW works better than SSB, and SSB better than FM? For that matter, why is PSK-31 pretty good, but modes like JT-65 and Olivia even better? It turns out that there are reasons for this founded in Information Theory, which began with a study of Morse Code. We’ll look at spectral power densities, information theory, the Shannon-Harley theorem, noise cliffs, coding theory, maximum likelihood decoding, convolutional coding, self-synchronizing codes, and more. We’ll even take a look at Fisher information and its relation to physics. Join me and explore why some modes work better, not just in how we experience them, but how they are impacted by their relationship to information theory.
