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...

Monetary Condition Index (MCI) can be used as a tool to assess the stance of monetary policy. This index is defined as the weighted average of different monetary transmission mechanism relative to their values in a base period. The weights in MC...
