Simulation of Differential Space Time Block Coding
Abstract: AbstractIn such a coherent system, the underlying assumption is that the channel does not change during one frame of data. Thus, it can also be interpreted as the frame length is chosen such that the path gain change during one frame is negligible. This is basically the quasi-static fading assumption that we have used so far. There is a bandwidth penalty due to the number of transmitted pilot symbols. Of …

Influence of Dielectric and Active layer Thickness on MgZnO Thin Film Transistor Electrical Characteristics
Abstract: From last decades, Thin Film Transistors Technology uses low-k dielectric material as an insulator. Insulator thickness plays an important role in device dimension. The insulating layer also known as the gate oxide separates the gate electrode from the channel region of the transistor. If the insulating layer is too thin, there is a greater chance that electrons can tunnel through the oxide layer, leading to leakage current. To mitigate this …
