A blind linear receiver for multi-antenna impulse radio ultra-wideband(UWB)communication systems was proposed.Without the need of channel information,specific properties of the received data imposed by the precoded space-time block codes(STBC

A fast encoding algorithm based on the mean square error (MSE) distortion for vector quantization is introduced. The vector, which is effectively constructed with wavelet transform (WT) coefficients of images, can simplify the realization of the non-

A high performance scalable image coding algorithm is proposed. The salient features of this algorithm are the ways to form and locate the significant clusters. Thanks to the list structure, the new coding algorithm achieves fine fractional bit-plane

A new Chinese teletext system based on the compatible extension of NAPLPS (North American Presentation-Level Protocol System) is reported. Three key problems-Chinese character extension, error protection, and PDI (picture description instruction) imp

In order to speed up the VQ encoding process, it is beneficial to firstly estimate how large the Euclidean distance is between the input vector and a candidate codeword by using appropriate low dimensional features of a vector instead of an immediate

A novel image fusion algorithm based on the support vector machine (SVM) is proposed. The original images are fused with different block sizes according to the positions of the original image blocks. Three features, i.e. the standard deviation, the D

As Tanner graphs (TG) of LDPC codes and channel noise distributions have some relationship, codes have considerable variation in performance even if they have a given code, given iterative decoding algorithm and given channel model. We present a new

The objective of image fusion is to combine the source images of the same scene to form one composite image that contains a more accurate description of the scene than any one of the individual source images. A multiresolution image fusion method and

A new multi-cell cellular configuration networks is provided for analysis of handover initiation probability, which is based on multi-beam base-station antenna splitting in the elevation-radiating plane. The sum of the mobile received signal power in

In this paper, we propose a video coding scheme that combines adaptive overlapped block motion compensation (AOBMC) with wavelet-based zerotree coding techniques. AOBMC combines two different motion models: conventional block motion compensation (CBM
