In order to keep up with the increasing demand on speed and reliability in modern wireless systems, new standards have to be introduced. By using Multiple Input Multiple Output technology (MIMO) and Continue reading
In the LTE mobile system, all cells use the same set of frequencies. This means that a user could experience interference from other cells. A method that has been studied in order to reduce this interference and thereby increase data rate or system throughput is to Continue reading
Error free transmission is one of the main aims in wireless communications. With the increase in multimedia applications, large amount of data is being transmitted over Continue reading
We conduct an exploration study of various bit precisions for Cholesky decomposition. This research focuses on obtaining the minimum required signal to noise ratio (SNR) in Cholesky decomposition by reducing the Continue reading
OFDM is mainly designed to combat the effect of multipath reception, by dividing the wide-band frequency selective fading channel into many Continue reading
Virtual multiple input multiple output (MIMO) techniques are used for energy efficient communication in wireless sensor networks. We investigate virtual MIMO for fixed and variable rates. We propose energy efficient routing based on virtual MIMO. The simulation results show that virtual MIMO based routing is more energy efficient as compared to SISO (single input single output) for larger distances.
In recent years, virtual MIMO has attracted a growing interest because of its energy efficiency in large field of networks. In virtual MIMO network, a group of sensors cooperate Continue reading
