Multiple-Input-Multiple-Output communication systems demand fast sphere decoding with high performance. We propose a high throughput soft-output fixed complexity sphere decoder (PFSD) that is parallel and has comparable performance to list fixed complexity sphere decoder (LFSD) and K-best sphere decoder. In addition, we propose a parallel QR decomposition… (More)
hardware software architecture for computation of discrete wavelet transform using the recursive merge filtering algorithm.
— In ad-hoc networks formed by battery powered nodes, the network lifetime can be significantly enhanced by incorporateing the battery properties in the routing protocol. In this paper, we propose such a routing mechanism BCRM, that enhances the network lifetime by letting some of the nodes recover part of their lost charge. This is done by putting the… (More)
In post-disaster situation, re-establishment of communication infrastructure is very critical task. For that delay tolerant network is used by smart phone users like volunteers or victims. In such fragile environment, data can be forwarded by store-carry-forward mechanism. So, for data delivery, multi-hop communication and proper cooperation among nodes are… (More)
Semantic web is the next generation web, which concerns the meaning of web documents It has the immense power to pull out the most relevant information from the web pages, which is also meaningful to any user, using software agents. In today's world, agent communication is not possible if concerned ontology is changed a little. We have pointed out this very… (More)
— Learning has become an essential part of many image and video processing systems, but it is not often used as an end-to-end solution. Some of the most successful demonstrations of end-to-end learning have been with convolutional, or shared weight networks. We are interested in how this approach can scale and have developed a flexible framework for… (More)
