  • Block coding method having increased flexibility in choice of code length or minimum code distance
    Patent number: 7117424
    Abstract: In a method of block coding, each character of the codeword may be thought of as a sum of characters of the message word, computed such that each message-word character that contributes to the sum is weighted by a respective weight coefficient. In the method described here, the weight coefficients are derived from a division polynomial of an elliptic curve.
