Query: Convolutional Polar Kernels   A family of polarizing kernels is presented together with
polynomial-complexity algorithm for computing scaling exponent. The proposed
convolutional polar kernels are based on convolutional polar codes, also known
as b-MERA codes. For these kernels, a polynomial-complexity algorithm is
proposed to find weight spectrum of unrecoverable erasure patterns, needed for
computing scaling exponent. As a result, we obtain scaling exponent and
polarization rate for convolutional polar kernels of size up to 1024.
