    A Review on Methodologies of Remote Sensing, GPS and GIS

    Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object. In modern usage, the term generally refers to the use of aerial sensor technologies to detect and classify objects on Earth (both on the surface, and in the atmosphere and oceans)...

    Advance Scheme for Localization Using Curvilinear Component Analysis

    The performance of applications of wireless sensor network depend upon the precise location of the nodes. The localization protocol patches together the relative coordinate, local maps into a global coordinate map. These protocols require some nodes that know their absolute coordinates, called anchor nodes. While many factors influence the node...

    Blind Channel Estimation Using Maximum Likelihood in OFDM Systems

    new blind channel estimation scheme for OFDM systems is based on the Maximum Likelihood (ML) principle. The approach combines different modulation schemes on adjacent subcarriers, such as BPSK and QPSK, to resolve phase ambiguity. By avoiding the use of second- and higher-order statistics, a very fast convergence rate is achieved....
