A message in the form of a sequence of bits is encoded into relatively short, non-binary signals. The message (or vector) is divided into two halves. The encoder first determines an encoding of the message into a vector half the length of the eventual encoded vector. The half-length vector forms the...http://www.google.com/patents/US20010016052?utm_source=gb-gplus-sharePatent US20010016052 - Method for encoding bits in a signal
