The focus of this work is to design parameters for shielded metal arc welding to ensure continuous and leak proof joints. To achieve the object an attempt has been made to selected important welding parameters. The selected welding parameters are welding current, welding speed, electrode angle and electrode angle. The selection is purely based on field expert’s suggestions, literature Survey an...

In this article, we consider the diversity-multiplexing tradeoff (DMT) of relay-assisted communication through correlated frequency selective fading channels. Recent results for relays in flat fading channels demonstrate a performance and implementation advantage in using relay selection as opposed to more complicated distributed space-time coding schemes. Motivated by these results, we explore...

Effective features can improve the performance of a model and help us understand characteristics underlying structure complex data. Previously proposed feature selection methods usually cannot retain more discriminative information. To address this shortcoming, we propose novel supervised orthogonal least square regression with weighting for selection. The optimization problem objective functio...

In this note, we propose a full-duplex decode-and-forward cooperative diversity scheme based on code division with orthogonal complementary codes. We consider a simple case in which a single user is assisted by a single relay to achieve cooperative diversity. When the cooperation is full-duplex, the operational delay of the relay makes the channel asynchronous and this may cause multiple-access...

Link adaptive relaying (LAR) is one of the most popular techniques which employs soft power scaling approaches at the relay nodes. On the other. Buffer-aided relaying is a new paradigm for wireless cooperative networks. Buffer-Aided Relaying With Adaptive Link Selection – Fixed and Mixed Rate. A wireless relay is a codecadaptive RF receiver with single channel relay. It helps easily deployment ...
