Abstract:

This paper investigates the asymptotic expansion of the maximum coding rate of a parallel Gaussian channel with feedback under the following setting: A peak power constraint is imposed on every transmitted codeword, and the average error probabilities of decoding the transmitted message are non-vanishing as the blocklength increases. This paper proves an upper bound on the first-and second-order asymptotics. Combined with existing achievability results, our result implies that the presence of feedback does not improve the first-and second-order asymptotics.
