  The growth of wireless communication technologies has been producing the
intense demand for high-speed, efficient, reliable voice & data communication.
As a result, third generation partnership project (3GPP) has implemented next
generation wireless communication technology long term evolution (LTE) which is
designed to increase the capacity and speed of existing mobile telephone & data
networks. LTE has adopted a multicarrier transmission technique known as
orthogonal frequency division multiplexing (OFDM). OFDM meets the LTE
requirement for spectrum flexibility and enables cost-efficient solutions for
very wide carriers. One major generic problem of OFDM technique is high peak to
average power ratio (PAPR) which is defined as the ratio of the peak power to
the average power of the OFDM signal. A trade-off is necessary for reducing
PAPR with increasing bit error rate (BER), computational complexity or data
rate loss etc. In this paper, two clipping based filtering methods have been
implemented & also analyzed their modulation effects on reducing PAPR.
