Optical Character Recognition is of great interest in machine learning and computer vision. Recognition of Bangla Character is a fast forwarded leap to this journey. Neural Network is the field of study in computer learning and its emerging day by day. Time and accuracy is the first concern in learning by machine. Many research works have been accomplished(More)
Almost Blank Subframes (ABSs) are an important part of enhanced Inter-Cell Interference Coordination in 3GPP standard. The concept of ABS is to blank some subframes of macro base stations (MBSs), therefore, PBSs can have no interference from MBSs during these periods. In this work, we propose Multi-tone ABS to enhance ABS, which is referred to single-tone(More)
In recent years, IEEE 802.11 wireless networks have become the most popular wireless technology. IEEE 802.11 supports multiple transmission rates. How to determine the appropriate transmission rate is challenging. In this paper, we propose a novel rate adaptation algorithm to tackle this problem. We utilize the maximum likelihood estimator to robustly(More)
Relay assignment means assigning the proper relay nodes (RN) to cell-edge users (UE) in order to exploit the spatial diversity through relay nodes and improve cell-edge performance. An optimal algorithm, called ORA, is to maximize the minimum data rate among all users. ORA is shown to find the optimal objective regardless the initial relay node. Although(More)
