Method and system for lossless value-location encoding

Abstract:

A method of encoding samples in a digital signal is provided that includes receiving a frame of N samples of the digital signal, determining L possible distinct data values in the N samples, determining a reference data value in the L possible distinct data values and a coding order of L-1 remaining possible distinct data values, wherein each of the L-1 remaining possible distinct data values is mapped to a position in the coding order, decomposing the N samples into L-1 coding vectors based on the coding order, wherein each coding vector identifies the locations of one of the L-1 remaining possible distinct data values in the N samples, and encoding the L-1 coding vectors.
