Polar Codes

Abstract

The purpose of the project is to determine if polar codes can outperform the forward error correction (FEC) currently used in Navy wireless communication systems. This report explains polar codes to non-specialists. The project team has written and tested software that implements several published polar coding algorithms. For comparison, the team has also implemented and tested other forward error correction methods: a turbo code, a low density parity check (LDPC) code, a Reed-Solomon code, and three convolutional codes. The team's preliminary conclusion is that polar codes can outperform the FEC currently used in some modes of Navy communications systems. Polar codes may also be able to outperform other codes that could be used to replace the current codes. Polar codes are more likely to be useful at higher data rates. Further research is needed to test polar codes, using more realistic models of Navy systems and their RF environments. Space and Naval Warfare Systems Center Pacific is now well positioned to do this further research.
