Interference is an inherent property of wireless multi-hop networks. In 802.11 wireless multi-hop networks, the impacting of physical interference on a transmission is complexity phenomenon that is the cause of degraded network performance. Several previous studies use analytical model to clarify the issue as a common approach. However, the models did not take fully considerations of physical inte... View full abstract»

This paper aims at evaluating pilot-based estimation technique for SC-FDMA LTE deployed via high altitude platforms (HAPS) channel. HAPS is a novel wireless infrastructure in which one of its applications is to carry cellular system such as 4G LTE. The problem of SC-FDMA LTE signal transmission over HAPS channel is due to multipath from objects nearby the mobile user. Signal at the receiver, which... View full abstract»

WiMAX is a wireless technology that was developed to overcome the limitations of wireline networks to meet the needs of Broadband Wireless Access (BWA) services to customers. As standardized, fixed WiMAX uses OFDM as its physical air interface. Therefore, it also suffers from high PAPR. To solve this problem, Partial Transmit Sequence (PTS) is used in this paper due to its better performance among... View full abstract»

In this paper we present the most implementable scheme for transmitting 19 channels electroencephalography (EEG) and speech signals simultaneously using a speech channel of telephony system. The proposed system works based on re-sampling, multiplexing and filtering concepts. Re-sampling is applied to adjust EEG sampling frequency such that appropriate with speech signal sampling frequency. The 19 ... View full abstract»

A Call Detail Record (CDR) is a data record produced by telecommunication equipment consisting of detail of call transaction logs. It contains valuable information for many purposes of several domains such as billing, fraud detection and analytical purposes. However, in the real world, these needs face a big data challenge. Billions CDRs are generated every day and the processing systems are expec... View full abstract»

Internet penetration in developing countries depend on a variety of factors, including the Gross Domestic Product (GDP), the density of telephone connections, and the density of personal computer users. Internet kiosks have been deployed in 21 rural ditrict areas of Garut Regency to facilitate internet access for local/district government as well as for the community who have no access to internet...

This paper presents 10dB planar directional coupler on FR4 substrate for Automatic Gain Control (AGC) system. The proposed design uses single section coupled line method that simulated using simulation software ADS 2011.10 and fabricated on FR4 substrate. The proposed design exhibits a return loss of -22dB, isolation of -26dB, a coupling level accuracy of 9.4dB and insertion loss of -0.7dB at 600M... View full abstract»

Long Term Evolution Advanced (LTE-A) is a promising technology to achieve peak data rate of up to 1 Gbit/s in the downlink and 500 Mbit/s in the uplink. Because adjacent cells employs the same frequency in universal frequency reuse scheme, interference between adjacent cells may degrade the bit rate, particularly at the cell edges. Inter-Cell Interference Coordination (ICIC) based on carrier aggre... View full abstract»

User authentication is a method for authenticating a user. Recently there were some authentication method proposed by researchers, such as a method proposed by Seung et al. where the user authentication process was done using biometric (fingerprint) and password. However, this method has weaknesses such as weak against fake user attack, high time complexity, and it is possible for fake device to o... View full abstract»

Among some of its duties, the cognitive radio's main role is to do spectrum sensing in the surrounding radio environment. In order to do mapping and can determine the frequency of use vacant frequencies which can be optimized for the use of cognitive radio communication. Even to the worst conditions in which the detector system has no knowledge of the signal and noise. There are several techniques... View full abstract»

The sensing applications of fiber Bragg gratings (FBGs) offer a high sensitivity, as well as other important advantages, such as real-time processing, long-term stability, immunity to electromagnetic interference, and convenient multiplexing capabilities.
