Bayesian decision feedback equalizer
(International University HCMC, Vietnam, 2009)
Bayesian is an elegant solution which is applied for digital communication
channel equalization, especially decision feedback equalizer. This is an extension to the
maximum a posteriori probability symbol-decision ...
Channel assignment for multiradio wireless mesh networks
(International University HCMC, Vietnam, 2009)
This thesis focuses on channel assignment problem which involves binding
each radio to a channel in such a way that efficient utilization of available channels
can be achieved. Some basic concepts of WMNs are introduced ...
Exploiting iterative demapping and decoding for multiple access
(International University HCMC, Vietnam, 2009)
We exploit the IDD for multiple access in
this thesis and provide a variety of MATLAB software-based simulation results to
demonstrate the advantage of the new multiple access technique over the conventional
ones such ...
Speech-to-text for Vietnamese language recognition with DSP & FPGA applications
(International University HCMC, Vietnam, 2009)
This thesis investigates the use of two methods - Hidden Markov Model (HMM) and
feed-forward multi-layer perceptrons trained by back-propagation - in Vietnamese
speech-to-text recognition. Besides this, the thesis ...
Research and Design Phase Shifter at High Frequency
(International University HCMC, Vietnam, 2009)
In this thesis, new side-coupled Schiffman phase shifters about 482 MHz, 85
degree phase shift and 45 degree are studied. The phase shift results for FR-4 material
(PCB material) used in the simulated models are very ...
RFID Reader Design for 125 KHz and 13.56 MHz Applications
(International University HCMC, Vietnam, 2009)
Deployment of radio frequency identification (RFID) system has been rapidly
growing and has the potential to affect many different industries and application such as:
tracking and identification, payment and stored value ...
Home remote control and security system using SMS and telephone
(International University HCMC, Vietnam, 2009)
In this thesis, I design a remote control of home security system with the SMS and telephone. The system consists of sensors such as: PIR sensor, smoke sensor, magnetic sensor, electric current sensor, etc for home security ...
Speed controller design for the line following robot
(International University HCMC, Vietnam, 2009)
Nowadays, automation is becoming the indispensable technology in the general development trend in the world. Many of countries apply new automatic technologies in many fields of life. Robots replace human works and more. ...
Zigbee wireless application for RFID door security system
(International University HCMC, Vietnam, 2009)
This thesis has three major purposes: (1) to establish a simple wireless sensor
network using two ZigBee enabled devices; (2) to incorporate the mentioned result
into a RFID security door; (3) to develop a computer program ...
A Design of transmitter for the High Speed Downlink Packet Access (HSDPA) system in 3G Mobile Networks
(International University HCMC, Vietnam, 2009)
From the achievements gained in the research as well as using cellular systems
such as GSM, CDMAOne, etc, HSDPA has been introduced in Release 5
specifications of the 3GPP WCDMA/UTRA-FDD standards as a new ...
