In 1949, Shannon derived his famous formula 1/2 log(1+SNR) for the capacity of the additive white Gaussian-noise (AWGN) channel. Designing an efficient code to achieve this capacity has been the holy grail of coding people ever since. This talk is concerned with a new class of capacity-achieving lattice codes, namely polar lattices. We show that the construction is explicit and efficient, and the overall complexity of encoding and decoding is O(N logN) for any fixed target error probability.
