    Design and performance analysis of 1.8 GHz low noise amplifier for wireless receiver application
    (Institute of Advanced Engineering and Science, 2017-06) Amin, A.A.,; Islam, M.S.,; Masud, M.A.,; Khan, M.N.H.
    In present stereo audio system is a most popular audio system for different purposes. Now a day’s stereo system is commonly used in communication and other purposes. Moreover Normalized Least Mean Square (NLMS) based adaptive filtering is an effective filtering process in case of communication and other applications. However adaptive filtering is an adaptive filter process to cancel out the noise from audio signal successfully. Hence the main objective of this paper is to design a NLMS adaptive filter which cancels out the noise from a noisy wave format stereo audio file. Moreover by varying the order of the adaptive filter (such as 8th, 16th, 32th and 64th), the performance of the NMLS adaptive filtered signal with respect to reference and noisy stereo audio signal are analyzed as well. © 2017 Institute of Advanced Engineering and Science.

    Design and performance analysis of 3.4 ghz rectangular microstrip patch antenna for wireless communication systems
    (Praise Worthy Prize S.r.l, 2017-02) Al Amin, A.,; Islam, M.,; Masud, M.A.,; Khan, N.H.,; Zavala, J.W.A.,; Islam, M.M.U.
    Wireless communication provides low-cost, high-speed and flexible communication in present days. Hence antenna plays a vital role in the wireless communication sector. The main concern of this paper is therefore to design a 3.4 GHz rectangular Microstrip patch antenna. Moreover, the feed probe based rectangular patch antenna will be designed. The performance of the designed rectangular patch antenna will be evaluated by analysing the major parameters of the simulation results. Hence the radiation pattern, gain, impedance matching and reflection coefficient or return loss calculation will be executed by the HFSS software to evaluate the performance of the antenna.
