In this paper, we discuss the question of closure conditions for dialogues in three different frameworks: W. C. Mann’s DMT framework, Vanderveken’s illocutionary theory of discourse and Asher and Lascarides SDRT approach. We are interested in formal frameworks that aim to describe the logical structure of conversations between diversely bounded agents who are to some extent rational, intelligen...

In this paper, we focus on the diversity-multiplexing tradeoff (DMT) in MIMO channels and introduce the development of DMT in MIMO channels. Zheng and Tse first proposed DMT in MIMO channels and based on their ideas, other researchers extended to many different aspects. We will study DMT in different MIMO fading channels, DMT curves and DMT under different protocols.

We present a new low-complexity method for the design of channel shortening equalizers for discrete multitone modulation systems using the eigenfilter approach. In contrast to other such methods which require a Cholesky decomposition for each delay parameter value used, ours requires only one such decomposition. Simulation results show that our method performs nearly optimally in terms of obser...

Assortative mating has been suggested to result in an increase in heritability and additive genetic variance through an increase in linkage disequilibrium. The impact of assortative mating on linkage disequilibrium was explicitly examined for the two-locus model of Wright (1921) and two selective assortative mating models. For the Wright (1921) model, when the proportion of assortative mating w...

The frequently reported amino acid covariation of the highly polymorphic human immunodeficiency virus type 1 (HIV-1) exterior envelope glycoprotein V3 region has been assumed to reflect fitness epistasis between residues. However, nonrandom association of amino acids, or linkage disequilibrium, has many possible causes, including population subdivision. If the amino acids at a set of sequence s...

The cyclic prefix is commonly used in the context of frequency domain equalization in DMT channels. In this paper we observe that it can be used in more general contexts and show its advantages in blind equalization, especially for non minimum phase channels.

In this report, we study the diversity-multiplexing tradeoff(DMT) in MIMO channels. DMT in MIMO channels is first introduced by Zheng and Tse. Based on their ideas, other researchers extended to different aspects. We will study DMT in two different aspects. In the first aspect, we will introduce DMT in different MIMO fading channels. In the second aspect, we will study different codes which wil...
