Abstract
Reconfiguring data in a manner that increases bit redundancy, and compressing the reconfigured data in an iterative or recursive manner until the desired compression ratio is obtained. The data are divided into one or more packets and the bits of the data in each packet are redistributed between two blocks. In one block the number of occurrences of adjacent bits of the '1' state is, on average, greater than the number of occurrences of adjacent bits of the '0' state and adjacent bits of differing states. In the other block the number of occurrences of adjacent bits of the '0' state is, on average, greater than the number of occurrences of adjacent bits of the '1' state and adjacent bits of differing states. The blocks are thus conducive to compression algorithms that exploit bit redundancy.
