Design and Implementation of OFDM Trans-Receiver for IEEE 802.11(WLAN)
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 1
Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation technique. OFDM provides high bandwidth efficiency because the carriers are orthogonal to each other’s and multiple carriers share the data among themselves. The main advantage of this transmission technique is their robustness to channel fading in wireless communication environment. Orthogonally placed sub carriers are used to carry the data from the transmitter end to the receiver end. Presence of guard band in this system deals with the problem of ISI and noise is minimized by larger number of sub carriers. This paper present transmission of an OFDM System using the software tool MATLAB and have undertaken various methods to reduce the errors in the system so that this system can be used more commonly and effectively

Coverage Analysis of Various Wireless Sensor Network Deployment Strategies
Abstract: Recent years have seen a developing interest in deploying large number of sensor nodes that coordinate in a distributed fashion on data gathering and analysing. These nodes can be deployed over a Wireles...
RANKING CONCEPT-BASED USER PROFILE FROM SEARCH ENGINE LOGS
Commercial search engines return roughly the same results for the same query, regardless of the user’s real interest. Since queries submitted to search engines tend to be short and ambiguous, they are not likely to...
A Novel Data Leakage Detection
Abstract: This paper contains concept of data leakage, its causes of leakage and different techniques to detect the data leakage. The value of the data is incredible, so it should not be leaked or altered. In the f...
Review on Implementation of Fir Adaptive Filter Using Distributed Arithmatic and Block Lms Algorithm
Adaptive filters play very important role in signal processing application. There are several algorithms for implementation of filters such as Least mean square (LMS), Recursive least square (RLS), etc. The LMS...
