This book is dedicated to my aunt, Melitta Gräfin von Stauffenberg
My aunt studied physics and worked in the field of aerodynamics. She developed new control devices for pilots and, as a test pilot herself, tested and analyzed the prototypes. She was a great example of how to successfully pursue one's mission. It was her example that inspired me to study physics and to pursue my specific goal of finding a perfect coding solution.
Thoughts on Coding
Forty years ago my thesis "Signalerkennung aus dem Rauschen" ("Identifying Signals from the Noise") at the Technical University of Aachen laid the foundation for this book, Perfect Radio Communication Coding. Back then, I decided to first earn my living in the industry, and so I sent my thoughts about coding into a far corner of my brain. This made particular sense, since the implementation of efficient coding applications, by today's standards, would not have been possible with the electronic components available at the time with their slow runtimes.
Captured by Improving Coding
This has changed markedly since the beginning of the new millenium. So it has been time to awaken my thoughts about coding, and whoever has been engaged in searching for codes will understand that one becomes eventually addicted to find the perfect solution. Therefore, when in 2005 I first found a fascinating coding method, the desire was engendered of course to present this to the communication industry. It was clear for me that I, as a no-name in this sector, would probably not be taken all too seriously. Then a friend gave me the advice I could apply for a patent instead of seeking a publication in a scientific magazine. This friend had been of the opinion I had invented the codes as such. He could not know that coding has a history of more than one hundred years.
J.J. Sylvester published already in the year 1867 an article over "Thoughts on Inverse Orthogonal Matrices", or the French Jacques Hadamard found in 1893 "Square Matrices of Orders 12 and 20, with Entries +/-, which had all their Rows Orthogonal". Likewise the US American mathematician J.L. Walsh described 1923 "A Closed Set of Orthogonal Functions". In 1923 the codes derived from these functions were named Hadamard-Walsh codes, or Walsh codes. Up to the 1990s they were among the most used codes in communication engineering, and other sciences. Further codes applied in today's communication technologies are Gold codes or Barker codes.
The Swiss mathematician Marcel J.E. Golay first introduced binary complementary sequences in 1949. In an article published at the beginning of the 1960s Golay presented another, complementary code set by multiplying complementary Golay codes with Walsh codes, named Golay-Walsh codes.
However, until today, none of the coding methods have succeeded in eliminating the recurring problems and errors in the transmission of data perceived as a nuisance by the user.
As mentioned above, the topic of coding has not lost its grip on me since 2005. By today an entire patent family has emerged - with patents in Germany, Europe and USA.

The Innovation arrives at a Perfect Solution
The innovation described in this book finally arrives at a perfect super-orthogonal solution for any communication engineering or other science. So after more than 140 years the problems have been solved in a perfect manner. This book presents a compendium and offers a comprehensive insight into the innovative possibilities of this perfect coding method.
All that remains is that the communication industry would acknowledge and apply this perfect solution as well. In fact, they have no choice. The only way to cope with the anticipated increase in data traffic over the next few years via air interface, that is to say "radio link", but also via fiber optic cable, or wireline, is through a perfect coding method, which has yet to be applied.
But now that the perfect solution is there, as you will find in the chapters of my book, the next generation of communication technology can be implemented.
