On the performance of cooperative cognitive networks with selection combining and proactive relay selection
Tra Thanh Luu, Lien Hong Pham, Son Que Vo, Khuong Van Ho
This paper proposes an outage analysis framework for cooperative cognitive networks with proactive relay selection and selection combining (SC) under licensed outage constraint, maximum transmit power constraint, independent non-identical (i.n.i) fading distributions, erroneous channel information, and licensed users’ interference. Towards this end, we firstly suggest power allocation for unlicens...... hiện toàn bộ
Application of the MQ RBF-FD method to calculating transient voltages of power transmission lines
Anh Pham Lan Vu, Viet Quoc Le, Tu Phan Vu
This paper presents an application of the Radial Basis Function – Based Finite Difference Method (RBF-FD) to solving the electrical transient problems defined by the time-dependent ordinary differential equations. In this method, the finite difference approximations of first- and second-order derivatives in time domain are formalated the same as those in space domain based on the MQ (Multiquadrics...... hiện toàn bộ
APPLYING TURBO CODE TO THIRD GENERAL MOBILE SYSTEM IMT-2000

Experiments of absolute positioning using BEIDOU in Vietnam
Lau Ngoc Nguyen
We research on absolute positioning using Beidou pseudo-range measurements collected in Ho Chi Minh City. Positional accuracy achieved is 2.3m, 4.5m and 3.9m for the North, East and height components compared to (0.8, 0.9, 1.7) of GPS and (2.0, 1.9, 4.1) of GLONASS. This result shows that in Vietnam we can use only BEIDOU system for positioning and also opens the possibility of incorporating posit...... hiện toàn bộ
Automatic detection of sleep onset in healthy adults
Bao Hoang Tran, Linh Quang Huynh, Anh Thi Ngoc Dinh, Khai Quoc Le
Sleep is very important for the health. Analyzing the polysomnography (PSG) helps us get valuable information to assess the quality of sleep. In this work, we develop a program to automatically detect the transition from wakefulness to sleep in adults. The accurate detection of the point of sleep onset occurs in the first time is useful for assessing the micro-structure of sleep. The proposed meth...... hiện toàn bộ
