THP
Ever heard of THP? It's a highly specialized engineering acronym that stands for Tomlinson-Harashima Precoding. It's terms like this that show online resources are not yet there when it comes to categorizing and organizing all human knowledge. In fact, they have a long way to go.
This term would be familiar to any advanced electrical engineering student today, yet neither Britannica, nor Wikipedia or Encarta offer a trace of it. A Google search for "THP" reveals plenty of results none of which are relevant. You would have to scroll several pages and really know what you are looking for to get anywhere. A search for "Tomlinson Harashima" reveals the first relevant hits, most of them either from course outlines or from papers published by schools such as Georgia Tech or UCLA.
Tomlinson in the US and Harashima in Japan independently introduced Tomlinson precoding as a technique for intersymbol interference mitigation. The structure that they presented is referred to as the Tomlinson-Harashima Precoder (THP). This technology is used in most of today's modems and DSL routers, etc. for dynamic signal equalization.
See a GA Tech reference in their Advanced Digital Communications course. I covered this in school myself, I think under the Communication Theory courses.
