摘要：
A recursive trellis-based algorithm is proposed for computing the probabilities arising in the successive cancellation (SC) decoding algorithm for polar codes with arbitrary linear kernels. This approach enables one to re-use intermediate values obtained at different phases. Arikan SC algorithm is shown to be a special case of this method.
