Low-density parity-check (LDPC) codes were first introduced in the early 1960s [1] and rediscovered in the mid-1990s [2]. Due to their good decoding performance, LDPC codes have been adopted for the ...
Abstract: Convolutionally precoded polar codes known as polarization-adjusted convolutional (PAC) codes are a promising variant of polar codes for short block lengths. The precoding in PAC codes has ...
