    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.

    Soliton: Gateway to future optical communication
    (Institute of Electrical and Electronics Engineers Inc., 2014-12-17) Ali, M.Z.,; Amin, A.A.,; Rahman, A.,; Islam, M.D.,; Wahiduzzaman, M.,; Paul, S.
    Soliton in fiber optic is a good solution to achieve the benefits of optical fiber without many of its limitations like the use of more repeaters or amplifiers in case of long haul communication. This work considered three particular long haul systems (Three segments of SEA-ME-WE 4 sub marine cable Networks) and shown the difference between the signal response in case of fiber optics with Gaussian pulse and with Soliton pulse. The parameters considered for this purpose are-pulse broadening ratio, phase displacement, attenuation and number of amplifiers used. By simulation, both the pulses were transmitted through optical amplifiers and analyzed their performances to show that the performances with Soliton pulse are better than the performances with Gaussian pulse over the long haul fiber optics communication.
