A wireless communication system for cellular technology is currently considered a very important topic for mobile phone. The design of such systems needs to include their multipath and fading main problems. In this paper, a MIMO-OFDM channel is designed and modeled to combat such problems, as well as STBS and directivity are also involved in this design to increase system reliability and enhance BER performance. The modeling and simulation process of the designed systems are carried out using Ma...

This paper presents the performance analysis of Bluetooth Low Energy (BLE) IEEE 802.15.1 standard in the piconet topology networks. The performance of the BLE network is analyzed in terms of connection interval (CI) and the number of slaves (NS) by using OMNET (v4.6) simulator. In the performance investigation process Data Length Extension (DLE) features is used with an application payload size of 60 bytes in order to achieve the best performance in a BLE (P2P) network. The modeled networks an...

In this paper, a modified SIS (susceptible-infected-susceptible) model with infective medium
and feedback mechanism on scale-free networks is presented. The model is suited to describe some epidemic spreading which are not only transmitting by
medium but also spreading between individuals by direct contacts. Considering
biological relevance and people’s subjecti ...

The whole globe is covered universally by water with a majority space. In
view of extraction of minerals as well as national security reasons, underwater
communication has become quite important for all the mankind. Researchers,
around the world are working for optimizing the multiple scheme in acoustic
channel. Recently, the researchers have reported valuable employability of IDMA
scheme in acoustic communica ...

In this paper electronic feed forward
equalization is performed to mitigate the link chromatic dispersion. The
equalizer coefficients are computed by a decision-directed process based on the
sign-sign least mean square and the recursive least square algorithm.
Therefore, this paper evaluates the performance of these algorithms in
chromatic dispersion compensation at bit rate of 10 Gb/s. This paper compares
these two adaptation algorithms for receiver based on analogue elec ...
