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.

Several 7-substituted derivatives of N,N-dimethyltryptamine (DMT) were prepared and evaluated in the rat fundus serotonin receptor assay and in a behavioral (discriminative stimulus) assay in rats. Both 7-Me- and 5-OMe-7-Me-DMT possess a higher pA2, and 5,7-(OMe)2-DMT a lower pA2, than that of DMT itself. Like DMT, all three of these compounds produce behavioral effects in rats which are simila...

this paper presents a description of the equipment, testing procedure, and methodology to obtain ground mechanical parameters. the p-y curves for laterally loaded piles are developed. methods for the development of p-y curves from pressure meter and dilatometer (dmt) test are described. p-y curves are used in the analysis to represent lateral soil-pile interaction. the pressure meter offers an ...

The energy efficiency of pulse-amplitude-modulated discrete multitone modulation (PAM-DMT) decreases as the modulation order of M-PAM modulation increases. Enhanced PAM-DMT (ePAM-DMT) was proposed as a solution to the reduced energy efficiency of PAM-DMT. This was achieved by allowing multiple streams of PAM-DMT to be superimposed and successively demodulated at the receiver side. In order to m...

Recently, discrete Fourier transform (DFT)-based discrete multitone modulation (DMT) systems have been widely applied to various applications. In this paper, we study a broader class of DMT systems using more general unitary matrices instead of DFT matrices. For this class, we will show how to design the optimal DMT systems over frequency-selective channels with colored noise. In addition, asym...

BACKGROUND Discontinuation of injectable disease-modifying therapy (DMT) for multiple sclerosis (MS) after a long period of relapse freedom is frequently considered, but data on post-cessation disease course are lacking. OBJECTIVES (1) To compare time to first relapse and disability progression among 'DMT stoppers' and propensity-score matched 'DMT stayers' in the MSBase Registry; (2) To iden...

The design of optimal DMT transceivers for distorted channel with colored noise has been of great interest. Of particular interest is the class of block based DMT, where the transmitter and the receiver consist of constant matrices. Two types of blockbased DMT transceivers will be considered: the DMT system with zero padding (ZP-DMT) and the DMT system with general prefix (GP-DMT). We will deri...

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...

The efficient operation of single-source, single-sink wireless networks is considered with the diversity-multiplexing gain tradeoff (DMT) as the measure of performance. Whereas in the case of a point-to-point MIMO channel the DMT is determined by the fading statistics, in the case of a network, the DMT is additionally, a function of the time schedule according to which the network is operated, ...
