A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

DESIGNING A FIR FILTER:
Following are the steps to design linear phase FIR filters Using Windowing Method.

I. Clearly specify the filter specifications.
Eg: Order = 30;
Sampling Rate = 8000 samples/sec
Cut off Freq. = 400 Hz.

II. Compute the cut-off frequency Wc
Eg: Wc = 2*pie* fc / Fs
= 2*pie* 400/8000
= 0.1*pie

III. Compute the desired Impulse Response h d (n) using particular Window
Eg: b_rect1=fir1 (order, Wc , 'high',boxcar(31));

IV. Convolve input sequence with truncate ....etc

I am Manzil Duarah a B.E final year student. My seminar topic for my final semester is A very linear low pass filter with automatic frequency tuning. I don't have the necessary documents for making the seminar report. So i wanted the full text document on this topic. So i would be very thankful if you help me out.
The abstract of the topic is as follows :

dear respected members,

please help this student by providing materials on sense response applications topic to prepare for giving a good seminar and if you can provide material along with a powerpoint presentation it would be great. At the very least i expect the members to share a couple of links whre i can find the materials and research papers needed on the topic.

thanks in advance.

with regards,
A BTECH student.... ....etc

Abstract—
The aliasing signal interferes with the actual signal and resembles more-like the original intermediate signal. This is called image frequency. To eliminate this image frequency a filter is to be designed in the RF (Radio Front) stage. At S-band microwave frequency (2 GHz to 4 GHz), the lumped components cannot be used due to distributed effects. Also, for the compactness of the filter, the distributed components are being used in microwave frequencies. Hence the coupled stage of microstrip filter with g ....etc

Abstract
Monitoring the health of power transformer is important for the reliability of electrical power supply. Conventional tests carried out on power transformers can only detect damage of permanent nature. Frequency Response Analysis (FRA) is found to be a useful tool for reliable detection of incipient mechanical fault in a transformer. There are various methods of evaluating the frequency spectrum to confirm the presence ....etc
