We analyze concatenation schemes of polar codes with outer binary BCH codes and convolutional codes. We show that both BCH-polar and Convolutional-polar (Conv-polar) codes can have frame error rate that decays exponentially with the frame length, which is a substantial improvement over standalone polar codes. With the increase in the cutoff rate of the channel after polarization, long constraint-length convolutional codes with sequential decoding suffice to achieve a frame error rate that… CONTINUE READING
