Abstract

There are several dimensions of web information retrieval using internet search engine. Increasing growth and updating in web world yield big challenges for search engine to retrieve the required information. The large size and dynamic nature of web highlights the need of continuous support and updating of web based information retrieval system. Keyword optimisation supports the search engine to find effective information retrieval from dynamically changing web environment.

Keywords

Optimize Search Technique, Keyword Based Information Retrieval System.

Abstract

With the concept of 3G & 4G services OCDMA is one of the important technologies, that provide a very high speed communication. In this technology multiple users can communicate simultaneously to transfer different kind of data. OCDMA enables the best use of available bandwidth and the spectrum to represent a cost efficient network. But in a network there is always the requirement to increase the security and the efficiency or the throughput of a multi user communication in the OCDMA network. The proposed work is about to increase the efficiency in a Noisy channel. Here the work will be performed on impulse noised network. We are here proposing the orthogonal approach along with OCDMA to improve the throughput. We are trying to show the results in terms of noise ratio and the derived throughput. The proposed work is about to reduce this packet loss and to increase the throughput in the noisy network. To overcome this drawback and to increase the throughput we are using the concept of OFDM along with CDMA. This concept is represented as the Orthogonal CDMA.
