    • An investigation on radiation characteristics of helical antennas 

      Nguyen, Truong The (International University HCMC, Vietnam, 2009)
      The Integral Equation (IE) method is used for analyzing the characteristics of the antenna based on the current distribution on the antenna. IE with the unknown of current distribution is solved by using numerical method ...

    • A study on PAPR reduction method for OFDM systems 

      Huy, Hoang Thai (International University HCMC, Vietnam, 2009)
      The Orthogonal Frequency Division Multiplexing (OFDM) has been used in many different wireless communication standards due to its many advantages. However, it has two major drawbacks, which are high peak-to-average power ...

    • A Design of transmitter for the High Speed Downlink Packet Access (HSDPA) system in 3G Mobile Networks 

      Phong, Nguyen Duc Bui (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 ...

    • A Design of Rake Receiver for the High Speed Downlink Packet Access (HSDPA) system in 3G Mobile Networks 

      Thong, Duong Minh (International University HCMC, Vietnam, 2009)
      This thesis addresses the problem of designing the receiver in high data rate systems. The case of multiple transmit antennas is also considered. Specific features of HSDPA system which are part of 3rd generation (3G) ...

    • 3D object recognition 

      Phuoc, Nguyen Dang (International University HCMC, Vietnam, 2009)
      This thesis implements a 3D object recognition system by using Matlab software to simulate two methods: Principal Component Analysis (PCA) and Artificial Neural Networks (ANN). One 3D object can be described with several ...
