Explicit construction of provably capacity-achieving code sequences with low encoding and decoding complexities has since then been an elusive goal. It has been seen that polar codes help in achieving capacity of the channel. The preliminary conclusion of this is that polar codes can outperform the FEC currently used in 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 systems and their RF environments. REFERENCES  E.
