Digital Data Compression Algorithm Performance Comparisons. Proposed NATO Standard Algorithm Provides Better Facsimile in a Noisy Communications Environment Than Present Tactical Digital Facsimile Algorithm.

Abstract

Performance of the NATO data compression algorithm in a noisy communication channel is superior to that of the present TDF data compression algorithm, provided that noise channel is not too harsh. Text is legible in a noise channel that has a bit error probability on the order 0.0003 (single bit errors). Multiple (burst) errors are not a problem provided the burst length does not exceed ten bits. Where actual burst length greatly exceeds the ten-bit (maximum) average expected in tactical situation noise, data compression algorithm performance may be poor, as with most data compression algorithms without a powerful noise protection algorithm. The NATO algorithm has enough compression to meet the current TDF performance specification, but its compression efficiency is lower than that of the TDF. The two algorithms have about the same complexity. (Author)
