Design of BCH Polarization Kernels With Reduced Processing Complexity
Elizaveta Moskovskaya, Peter Trifonov · IEEE Communications Letters · 2020
The letter introduces a construction of extended BCH polarization kernels, which admit simple computation of the probabilities or log-likelihood ratios arising in the successive cancellation decoding algorithm. The kernels are obtained by finding a column permutation of extended BCH kernels with natural column order, such that the total complexity of the associated trellises is minimized.
