"Many years ago , on the eve of World War II, a well-known actress of the day and my father, an avant-garde American composer, while at a dinner party, thought up an interesting scheme to control armed torpedoes over long distances without the enemy detecting them or jamming their transmissions. While they had the foresight to patent their invention, the term of the patent lapsed without either of them realizing any money from their invention, which formed the basis of what was to later become spread-spectrum communications. This invention becomes even more incredible when you consider that it came before the invention of digital electronics.. however, it makes very substantial use of several key digital concepts. Yes, the term "ahead of it's time" would apply here, because over 50 years later, as high-speed microprocessors become inexpensive, spread-spectrum communications- Hedy ' Lamarr ' and my father, George Antheils ' ' secret communications system ' - adapted to use today's ultrafast microprocessors- is coming into it's own as a effective and inexpensive way to communicate over long distances, privately and efficiently. Spread-spectrum forms the basic principle that enables the simultaneous multi-channel operation of modern digital cellular telephony." (excerpted)
