Abstract:
1. An error correction method for use in a digital communications system comprising: grouping incoming message bits from a message source into a plurality of groups, each group containing N bits, wherein said N bits range from 2-5; creating discrete analog samples from each group of N bits; transforming each of the analog samples into coefficient samples with a real 4-square ortho-normal matrix to create ortho-normal real value samples; generating additional coefficient samples using d receiving the ortho-normal samples and the additional coefficient samples at the receiver; applying the additional coefficient samples with a set of error policies on said ortho-normal real value samples to correct an error in any of the ortho-normal real value samples; processing the corrected ortho-normal real value samples by an invertible ortho-normal transform producing estimated discrete samples by transforming the corrected ortho-normal samples; and decoding the estimated discrete samples to provide received message bits which match the incoming message bits.
