  Orthogonal frequency division multiplexing (OFDM) is an emerging research
field of wireless communication. It is one of the most proficient multi-carrier
transmission techniques widely used today as broadband wired & wireless
applications having several attributes such as provides greater immunity to
multipath fading & impulse noise, eliminating inter symbol interference (ISI),
inter carrier interference (ICI) & the need for equalizers. OFDM signals have a
general problem of 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. The
drawback of high PAPR is that the dynamic range of the power amplifier (PA) and
digital-to-analog converter (DAC). In this paper, an improved scheme of
amplitude clipping & filtering method is proposed and implemented which shows
the significant improvement in case of PAPR reduction while increasing slight
BER compare to an existing method. Also, the comparative studies of different
parameters will be covered.
