ABSTRACT:
In a coding method, a (2N−1)storiginal block of m bits is encoded as an A type weighted block of n bits and a 2Nthoriginal block of m bits is encoded as a B type weighted block of n bits. In a decoding method, if a weighted block of n bits is the A type block, the weighted block of n bits is decoded as the (2N−1)storiginal block of m bits, and if otherwise, the weighted block of n bits is decoded as the 2Nthoriginal block of m bits.
