Performance analysis of a space time block coded MIMO system over faded channel
(BRAC University, 2011-04-20)
Performance analysis will be carried out for a MIMO wireless link with space time block
coding to find the performance over a Raleigh fading channel. The expression for the
signal and SNR at the receiver output will be ...
Contingency analysis and reliability evaluation of Bangladesh power system
(BRAC University, 2011-04)
An over-riding factor in the operation of the power system is the desire to maintain security and expectable reliability level in all the sectors- power generation, transmission and distribution. System security can be ...

Developing a remote control for digital data transmission using infrared and rario frequency : wireless communication
(BRAC University, 2013-04-27)
In this work we will first realize a TV remote control system. The system will allow digital data to be transmitted over a significant distance using a radio link where the input will be infrared (IR) signal. As a result ...
Study of soliton propagation inside optical fiber for ultra-short pulse
(BRAC University, 2011-12-15)
We will study the pulse propagation in optical fiber. The effect of non-linearity and dispersion of the pulse propagation causes temporal spreading of pulse and it can be compensated by nonlinear effect. When the effects ...
