Capacity and BER Performance Analysis of Single Cell Massive MIMO with Various Precoding Techniques
Abstract: AbstractMassive Multi Input Multi Output (MIMO) is one of the promising technologies which will facilitate the 5th generation wireless communication system (5G) in the near future. It also goes by other names such as, large MIMO, hyper MIMO, full-dimension MIMO and ARGOS. In this technology the Base Station is incorporated with a large number of transmitting antennas (e.g., Hundreds, thousands). A large number of antenna help to focus the energy …

Library Resource Sharing and Networking
Abstract: AbstractLibraries in the past had only written or printed documents. Written documents are manuscripts. These documents are always kept away and are not shared with other libraries. The users are expected to visit the library for consultation. The other category; the books were also not loaned to everyone and they were seldom shared with other libraries. With the introduction of printing by movable types, books started appearing in good number …

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 …

Evaluation of Effect of Seeds and Downloaders on the Performance of BitTorrent Network using Markov Chain Modeling
Abstract: AbstractIn this paper, we are using existing Markov chain model to study the effect of count of seeds and downloaders on transition rates, which is an important parameter in Markov chain modeling. As of now, many analytical modeling techniques are used to evaluate the performance of BitTorrent network and Markov chain model is found to be an effective, accurate and extendible one. Many researchers have studied BitTorrent networks to evaluate …
