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...

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...

T here is always uncertainty about the soundness of an economic model’s structure and parameters. Therefore, central banks normally face with uncertainty about the key economic explanatory relationships. So, policymaker should take into account the uncertainty in formulating monetary policies. The present study is aimed to examine robust optimal monetary policy under uncertainty, by ...

Since the global financial crisis, relationships between gender and political economy have received renewed attention, emphasising change as well continuities. Similarly, a recent return of attention to interrelation masculinity neoliberalism has stressed historicity specificity in nature these relationships. However, question how articulations are socially politically made within contested fie...

This is a special conference for the Federal Reserve Bank of Boston, and for me personally. The role of monetary aggregates in monetary policy was intensely controversial when I joined the staff of the Board of Governors in May 1969. I was immediately asked to join the staff of the newly formed FOMC Committee on the Directive. Governor Sherman Maisel chaired that committee; the other two member...

the history of monetary policy in iran, judging by their performance in keeping the value of the currency, maintaining a steady growth in the gross domestic product, faltering investment, show that monetary policy has not been a portrait of consistent successes, to say the least. as a result of the recent studies two rules have emerged as guideline for policy makers: taylor rule and mccallum ru...

W hat is today’s big monetary policy issue? It is, surely, the extraordinary volatility of the financial markets and the wide quality spreads that opened up between riskier bonds and Treasury bonds following the Russian default in mid-August 1998. No one forecast these problems; the financial-market upset certainly was not a real, live policy issue back in the spring and early summer. We should...
