An efficient UE cluster head selection algorithm in wireless sensor networks and cellular networks
Journal of Electronics (China) - Tập 30 - Trang 57-65 - 2013
Wireless Sensor Networks (WSNs) have been applied in many different areas. Energy efficient algorithms and protocols have become one of the most challenging issues for WSN. Many researchers focused on developing energy efficient clustering algorithms for WSN, but less research has been concerned in the mobile User Equipment (UE) acting as a Cluster Head (CH) for data transmission between cellular ......
Novel two-layer motion estimation for video coding
Journal of Electronics (China) - Tập 31 - Trang 354-365 - 2014
In this paper, we proposed a novel Two-layer Motion Estimation (TME) which searches motion vectors on two layers with partial distortion measures in order to reduce the overwhelming computational complexity of Motion Estimation (ME) in video coding. A layer is an image which is derived from the reference frame such that the sum of a block of pixels in the reference frame determines the point of a ......
A new Ad Hoc routing algorithm based on minimizing the channel handoff
Journal of Electronics (China) - Tập 27 - Trang 749-755 - 2011
How to improve the performance of the wireless Ad Hoc network by utilizing the spectrum resources efficiently has become a hot research topic in recent years. In this paper we propose a reactive routing algorithm that supports multiple channels to improve the performance of the Ad Hoc network based on the minimizing of the channel handoff. Our approach allocates the communication channel during th......
Automatic orthogonalization detection approach for GS algorithm
Journal of Electronics (China) - Tập 12 - Trang 186-192 - 1995
Gram-Schmidt orthogonalization algorithm is an interesting theme in the field of adaptive beam-forming and filtering as a fast algorithm. However, a key problem associated with this algorithm is that the number of orthogonalization, namely, the dimensions of interference subspace, is required to know prior. In this paper we derive a threshold and adopt it to detect the number of orthogonalization ......
Performance analysis of the music algorithm in the presence of amplitude and phase error
Journal of Electronics (China) - Tập 15 - Trang 226-232 - 1998
This paper presents the performance analysis of the MUSIC algorithm in the presence of channel amplitude and phase Error. Theoretical expression for the error of DOA estimating with MUSIC algorithm and Cramer-Rao bound are derived. It is compared with simulations performed for some representative cases. The results of theoretical expression and simulation show that existence of these errors will i......
Constacyclic codes of arbitrary lengths over ring $$Z_{p^m } + vZ_{p^m }$$
Journal of Electronics (China) - Tập 31 - Trang 222-226 - 2014
By constructing a Gray map, constacyclic codes of arbitrary lengths over ring
$$R = Z_{p^m } + vZ_{p^m }$$
are studied, where v
2 = v The structure of constacyclic codes over R and their dual codes are obtained. A necessary and sufficient condition for a linear code to be self-dual const......
A realistic model of neural networks
Journal of Electronics (China) - - 1992
A realistic model of neural networks was proposed in this paper. The dynamic process of neural impulse discharging was considered. The equations of the model correspond to postsynaptic potentials, receptor potentials, initial segment graded potentials and the impulse train along the axon respectively. To solve the equations numerically, a recurrent algorithm and its corresponding flow chart was al......
Discriminant Independent Component Analysis as a subspace representation
Journal of Electronics (China) - Tập 23 - Trang 103-106 - 2006
Subspace modeling plays an important role in face recognition. Independent Component Analysis (ICA), a multivariable statistical analysis technique, can be seen as an extension of traditional Principal Component Analysis (PCA) technique, which addresses high order statistics as well as second order statistics. In this paper, a new scheme of subspace-based representation called Discriminant Indepen......
