In this paper the dispersion of graphene in to epoxy system by using sonication as well as dispersion states and reaggreation properties have been studied. The reaggreation property was measured by using UV spectroscopy.. The decrease in light transmittance was about 80.6 to 60.3% in liquid epoxy after 10mins. which mainly depends on the sonication time and temperature.

It is because of its several advantages such as high spectral efficiency, low implementation complexity, less vulnerability to echoes and non–linear distortion. However, it has few limitations such as peak-to-average-power ratio (PAPR) and bit error rate (BER), which determines the system's power efficiency. High PAPR is one of the major drawbacks in OFDM systems, which causes a significant level of signal distortions, when the modulated signals are amplified through high power amplifiers (HPAs). Also, a high PAPR and, in addition, high noise (e.g. AWGN) may significantly distort the signal, resulting in high BER on demodulation of the received signal. Therefore, PAPR & BER reduction is very essential. For this purpose, the research reported in this paper is focused on providing a solution to the same problem. More speci...
