Power Line Carrier communication is a fast-developing technology and finds many applications, such as automatic meter-reading system. However, as the one-hop communication distance is limited due to the channel attenuation and strong line noises, relay technology is necessary for PLC networking. Among all the relay methods, Ant Colony Algorithm is a promising one but still with some shortcomings, such as the long searching time and the inclination to find a local optimal solution. This article provided a simple but effective algorithm to make use of the available path information to speed up the searching process, and reach the global optimal path. Experiment results show the presented algorithm can improve convergence time by 13.5%.

A high performance 2T gain cell memory device is demonstrated for the first time in 0.13μm CMOS technology. A novel asymmetric source and drain doping profile combined with high threshold voltage (Vt) scheme for the write transistor is introduced to reduce the cell leakage and then improve data retention characteristics. Experimental results show a data retention of 698μs @85°C with 99.9% yield, which proves that the proposed 2T gain cell may be a very promising candidate for low cost and high density eDRAM application.

This paper proposes an image green enhancement method based on luminance and hue. In the current algorithm, there are two main issues, i.e., the presence of over-saturation and color deviation, which can not satisfy people's demands for stronger green enhancement. To solve these problems, the correct mathematical model about luminance on chrominance constraint relations is proposed and an appropriate product factor list is obtained. The MATlab simulation images show that the proposed method effectively enhances the green color and at the same time avoid the problems of over-saturation and color deviation.

Through Silicon Via (TSV) is now becoming one of the most critical and enabling technologies for 3-D *** interconnection of several chips offered by TSV will result in improved performance and functionality, miniaturization in size and weight and reduced power consumption. Cu as TSV filling material is well used in the traditional damascene process. In this work, Cu seed deposition in high aspect ratio features using traditional PVD tool is developed and seamless TSV Cu filling is achieved. The TSV via dishing in Cu CMP soft landing step is also discussed. Finally, the TSV via resistance is extracted from the special designed test structure without additional bonding wafer or backside patterning.

This paper proposes a novel demosaicing algorithm based on improved gradients with color correlation. Compared to conventional method, especially on region with dense lines and textures, the proposed method may reduce the probability on the edge direction judgment, which may lead to obvious artifacts. The improved adaptive gradients calculation uses color correlation information. The proposed method can effectively suppress the artifacts and increase average PSNR on R, G and B channels by 0.59db, 0.69db and 0.56db respectively.

As an extension of binary low-density parity-check (LDPC) codes, non-binary LDPC (NB-LDPC) codes show significantly better performance when the code length is moderate or small. Recently, enhanced iterative hard reliability based (EIHRB) decoding algorithm is proposed to reduce the computation complexity. However, the EIHRB algorithm suffers a lot from significant performance degradation when the column weight is small. In this paper, a symbol reliability based (SRB) decoding algorithm, which also performs well when the column weight is low, is proposed for NB-LDPC decoding to improve the decoding performance. With the same maximum iteration number, around 0.38 dB extra coding gain is achieved. Furthermore, the corresponding efficient decoder architecture is proposed. Comparison results have shown that the proposed SRB algorithm can not only achieve good coding gain, but the cost for hardware implementation is reasonable.
