The implementation and integration of a high frequency synthesizer for RF super heterodyne AM-SSB System
(BRAC University, 2010)
The increasingly popular wireless communication systems need good power sorces with high frequency. Wi Will be designing power sources operating at 25 MHz and power sources with a 25 MHz indoor wireless super heterodyne ...
Design and development of microcontroller based ECG simulator
(BRAC University, 2010-12)
For the training of doctors as well as for design, development and testing of automatic ECG(Electrocardiogram) machines, a subject with a known abnormality of heart is essentially required. ECG simulator is an electronic ...
Performance analysis of wireless communication link using orthogonal FDM (OFDM) over faded channel and space time block code
(BRAC University, 2010-08)
Analysis will be carried out for an OFDM wireless communication system using space time block code (STBC) at the transmitter and considering the effect and the wireless channel like delay spread and fading. The analysis ...
An enhanced tree based key management scheme for secure communication of wireless sensory network
(BRAC University, 2010-04)
Wireless sensor networks (WSN) are mobile ad hoc networks in which sensors have limited resources and communication capabilities. Secure communications in some wireless sensor networks are critical. Key management is the ...
