Detection Of Mdpsk In Fading Channels Using Gaussian Particle Filter, P. Sudhakar 2020 VIEW, Visakhapatnam,AP,India. 81818app手机版下载

Detection Of Mdpsk In Fading Channels Using Gaussian Particle Filter, P. Sudhakar

International Journal of Power System Operation and Energy Management

We propose Gaussian particle filtering approach for solving the problem of corrupting the MDPSK signals by fading as well as noise. Particle filtering is a powerful tool for non linear problems but it faces sampling degeneration problem which leads to re‐sampling process. Gaussian Particle Filtering doesn’t need re‐sampling process because it approximates the posterior distribution as Gaussian.GPF is preferable than PF for fading channels.

An Integration Approach For Heterogeneous Distributed Database Transaction Protocols, Dharavath Ramesh, Saritha Vemuri, Vijay Kumarv

International Journal of Computer Science and Informatics

Integration is commonly used for summarizing information held in very large databases which are encountered in data warehousing, large scale transaction management, and statistical databases. Such applications often involve distributed databases that have developed independently and therefore may exhibit incompatibility, heterogeneity, and data inconsistency. We are here concerned with the integration that has heterogeneous classification schemes where local ontology’s, in the form of such classification schemes, may be mapped onto a common ontology. Existing transaction protocols typically rely on compensating transactions to handle exceptional conditions. In this paper, we develop an approach that can handle data inconsistencies and identify ...
