Performance Analysis For SNR Vs BER Of Optical System Using MLSE Equalizer With Different Modulation Technique

In This paper we present an analytical approach to evaluate the performance analysis of SNR V/s BER of Optical System using MLSE Equalizer in fiber channel through the BPSK, QPSK, 64QAM &16QAM Modulation Technique. Finally we are comparing BER performance in Optical system using MLSE Equalizer through the modulation technique.

QUICK ASSESSMENT OF GROUND WATER BY ELECTRICAL RESISTIVITY SURVEY

Next to air and food, the other most important requirement for existence of mankind is water. Rapid growth in population and industrial development has made it difficult to survive on existing limited water resources. The complex geological formations have made it difficult to locate the large quantities of quality water resources. The surface water level is rapidly depleting and thus has made us rely more and more on ground water sources. DOWSING is the oldest method that is used to locate the ground water resources.
