In this paper we investigate the typical behaviour of minimum distance and ML word error probability of a serial turbo concatenation with random interleaver, when the interleaver length N goes to infinity. Our main result shows that the word error probability P(e) goes to zero subexponentially in N with probability one. While it is known that 10glE[P(e)]/logN converges to a constant, we prove that
We extend Burnashev's [5] classic result for the error exponent of discrete memoryless channels with feedback to the case of Markov channels with ISI and feedback. This is a nontrivial extension of our previous work [6] where we treated the case of Markov channels with feedback but without ISI. Tools from stochastic control theory are used to treat the case with ISI.
The problem of the minimum Bhattacharyya distance of group codes over symmetric channels is addressed. Ensembles of ℤm-linear codes are introduced and their typical minimum distance characterized in terms of the Gilbert-Varshamov distances associated to the subgroups of ℤm. For the AWGN channel with 8-PSK as input it is shown that the typical ℤ8 -linear code achieves the Gilbert-Varshamov bound.
We consider the reliability function of Markov channels with feedback and variable length channel codes. We extend Burnashev's [3] classic result to this case and present a single letter characterization for the reliability function.
Swedish Central Bank Policy in the Post-War Period: Some CommentsThis article discusses the nature of the actions taken by the Swedish central bank - the Riksbank - in the post-war period and examines some of the consequences of these measures. In this context the views of the critics of the Riksbank are presented. Further, a review of the Riksbank’s measures is given. A distinction between moneta

Vietnam is one of the countries most vulnerable to climate change impacts, especially from extreme weather events such as storms and floods. Thus, climate change adaptation is crucial, especially for natural resource-dependent farmers. Based on a qualitative research approach using a feminist political ecology lens, this article investigates gendered patterns of rural agrarian livelihoods and clim
