DESCRIPTION:In 1949\, Shannon derived his famous formula 1/2 log(1+SNR) fo
 r the capacity of the additive white Gaussian-noise (AWGN) channel. Design
 ing 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 capac
 ity-achieving lattice codes\, namely polar lattices. We show that the cons
 truction is explicit and efficient\, and the overall complexity of encodin
 g and decoding is O(N logN) for any fixed target error probability.\n\n*BI
