Method and apparatus for transmitting a signal at a predetermined level of reliability using retransmission of erroneously transmitted frames so as to minimize total transmission energy. The transmitting station evaluates the frame error rate (FER) as a function of energy. Next, the transmitting station...http://www.google.de/patents/US6771700?utm_source=gb-gplus-sharePatent US6771700 - Method and apparatus for minimizing total transmission energy in a communication system employing retransmission of frame received in error
