This paper, proposes a Radio Network Planning for Fixed WiMax Network for Dhaka City. To develop the plan a cell radius of 400 meter is assumed. For the justification of this assumption several numbers of experimental analyses are done. Two experiments are executed to know the data speed with respect to the distance both for uplink and downlink communication. Another two experiments are executed for both downlink and uplink to know the most preferable WiMax frequency band for Dhaka city. The experiments are done for different types of modulation schemes. From the performance tests it is decided that the designed network will perform pretty well with the cell radius of 400 meter and at the frequency band of 2.5 GHz.

The emergence of WiMAX has attracted significant interests from all fields of wireless communications. WiMAX has been tipped to bring a revolution in the way where broadband services have been used today; those have been strengthened by the optimization of RF. The systematic investigation to establish facts of necessary modification about the theory for smooth optimization is targeted. This paper has considered the map outage factor of the objective function for the invention of a method to produce suitable values which help to realize better output. Simulation results found to be more precise over conventional RF of WiMAX in finding the modification of the existing theory.

Many recommendations are proposed for accommodating multimedia content into wireless media with lower bandwidth. These formats of the content have been developed with different objectives. Now it has become really challenging to compare all these diversified formats. In this paper, we proposed an algorithm to compare the FLV, MPEG4 and 3GP format of multimedia content using the parameters that determines their performance in wireless network. Finally, exhaustive experiments are done and the results are shown to demonstrate the merits and capabilities of the different file formats.

In this paper we present a method for Bangla speech generation from Bangla PDF document. Our main goal is to generate almost natural speech from Bangla PDF document. For this we have proposed a method which performs three major tasks. One is PDF to text conversion, then text to ASCII conversion, and then follows the character and modifier rules while reading text and finally speech generation from the concatenate sound files of text. We have analyzed the proposed method and the existing methods with respect to error rate of reading all the Bangla words and also the time complexity.

To support IP-mobility of networks in motion, IETF proposed Network Mobility (NEMO) protocol that uses various signaling messages to ensure connectivity of the mobile nodes with the Internet. However, there has been no comprehensive cost analysis of mobility protocol entities that considers all possible costs. In this paper, we have developed analytical models to estimate total costs of key mobility management entities of NEMO. We have presented numerical results to demonstrate the impact of network size, mobility rate, traffic rate and data volume on these costs. Our cost analysis will thus help network engineers in estimating actual resource requirements for the key entities of the network in future design.

3rd Generation Partnership Project Long Term Evolution (3GPP LTE) has adopted orthogonal frequency division multiple access (OFDMA) as downlink and single carrier frequency division multiple access (SC-FDMA) as uplink for multiple access scheme. SC-FDMA is adopted in uplink due to its low peak to average power ratio (PAPR). To reduce PAPR in OFDMA, several techniques are used in literature. SC-FDMA is adopted in 3GPP as it shows better PAPR characteristics than OFDMA. Many researches are still going on to find the impact of different parameters on PAPR in SC-FDMA. In this paper, a PAPR reduction technique is proposed where the precoding is done in the first step and at the second step, clipping is performed using SC-FDMA environment. Result shows that the PAPR is reduced at the increase in number of clips.

The increased prevalence of mobile phones provides exciting opportunities for the growth of mobile banking (m-banking). This article reviews the emerging research literature on m-banking. It presents a classification framework for m-banking research based on 65 m-banking articles published between 2000 and mid-2010 in Information Systems (IS), technology innovation, management, and marketing journals, and major IS conferences. These articles are classified into five main categories: m-banking overview and conceptual issues, m-banking applications and cases, m-banking behavioural issues, infrastructures of mobile users and networks, and strategic, legal and ethical issues. It is expected that the comprehensive list of references and assessments presented in this article will provide a useful anatomy of young m-banking literature to anyone who is interested in m-banking and help stimulate further interest.

Single Wall Carbon Nanotubes exhibit outstanding contributions in the recent VLSI interconnections. Interconnects analyzed in VLSI circuits depends on the electrical properties of carbon nanotubes. Metallic carbon nanotubes are very distinct for their ballistic conductivity in nano level interconnections. Different peaks are analyzed in Raman spectroscopy technique for characterizing metallic carbon nanotubes. The performance analysis of metallic carbon nanotubes is compared with the conventional Cu interconnects. In this study we analyzed resistivity and capacitance of carbon nanotubes interconnects which indicates carbon nanotubes interconnect are the most prominent solution for the future VLSI technologies.

In this paper least square (LS) and linear minimum mean square error (LMMSE) channel estimation (CE) techniques are presented for long term evolution (LTE) single carrier-frequency division multiplexing (SC-FDMA) systems. The main purpose of LTE is to increases data rate but energy utilization both on the mobile terminal as well as network side is important. For doing this, major challenges for LTE terminal are CE and equalization. This paper discusses the CE techniques and challenges imposed by developments in the LTE terminal implementation. Simulation results shows that the LMMSE CE algorithms outperforms the LS in term of mean square error (MSE) by more than around 3dB. Hence, based on a given LTE systems resources and specifications, a appropriate method among the presented methods can be applied.

Gene Regulatory Network (GRN) is an abstract mapping of gene regulations in living cells that can help to predict the system behavior of living organisms. In this research, we use a model based inference method to reconstruct GRN from gene expression data. We use linear time variant model which is of particular interest among all other models because of its capability of discovering the non-linear interactions among genes in a reasonably short time even while dealing with noisy time-series data. Here, Differential Evolution (DE), a versatile, robust and well-known Evolutionary Algorithm (EA) has been used. The potency of the proposed method has been verified in gene network reconstruction experiments, varying the network dimension and characteristics, the amount of gene expression data used for inference, and the noise level present in gene expression profiles. Real expression dataset of SOS DNA repair system in Escherichia coli is used to reconstruct the regulatory network. All these experiments have proved the efficacy of the proposed reconstruction method.
