Concatenated Reed-Solomon and Polarization-Adjusted Convolutional (PAC) Codes

Abstract

Two concatenated coding schemes incorporating algebraic Reed-Solomon (RS) codes and polarization-adjusted convolutional (PAC) codes are proposed. Simulation results show that at a bit error rate of 10−5 , a concatenated scheme using RS and PAC codes has more than 0.25 dB coding gain over the NASA standard concatenation scheme, which uses RS and convolutional codes.
