Value Measurement of Services of 4G IMT-A Systems: A Perspective of Bangladesh
Abstract: The International Mobile Telecommunication Advanced (IMT-A) is the 4th generation (4G) of mobile communication standards. Since 3rd generation (3G) has not been successfully captured the market in many parts of the world and in the very early stage in Bangladesh, 4G seems to be the emerging technologies to address the user needs in Bangladesh. In this paper, we focus on the value measurement of services of IMT-A systems in the …

Design Of A Quadcopter Using PID Control Algorithm
Abstract: The military use of quadcopter has grown because of its ability to operate in dangerous locations while keeping human operators safe. Here, a low-cost hover control mechanism is developed and implemented on a microcontroller. Flight control becomes simpler as the quadcopter hovers at a constant level from ground by itself, at the same time making it too easy to maneuver at heights and perform tasks such as imaging. A PID …

A NUMERICAL SIMULATION OF OPTICAL RECEIVER PERFORMANCE OF WDM SIGNALS IN A PON
Abstract: This work presents MATLAB 7.9 model of wavelength division multiplexed (WDM) communication system for evaluating the performance of optical receiver simulation of WDM-PON (passive optical network). This paper attempts to focus on eliminating the channel internal noise due to number of users at different noise power levels, iterations, values of BER (bit error rate) and error count within time elapsed in seconds. Optical communication systems have good speed, accuracy and …

Study of Spectrum Sensing Techniques for OFDM-based Cognitive Radio
Abstract: Nowadays OFDM (Orthogonal Frequency Division Multiplexing) techniques are adopted by many existing or progressing wireless communication standards. OFDM’s sensing and spectrum shaping capabilities together with its flexibility and adaptivity make it the best transmission technology for CR system. Spectrum sensing helps to detect the spectrum holes (unutilized bands of the spectrum) providing high spectral resolution capability. Thus, a robust spectrum sensing algorithm for OFDM modulated signals is highly decide to …
