| Summary: | This paper work focuses on performance analysis of PAPR
reduction of orthogonal frequency division multiplexing
(OFDM) using amplitude clipping & filtering based design. Now
a days one of the most proficient multi-carrier transmission
techniques widely used today is orthogonal frequency division
multiplexing (OFDM) which has been implemented by the next
generation wireless communication technology: Long Term
Evolution (LTE). Extra robustness to multipath fading and
impulse noise is provided OFDM. It eliminates inter symbol
interference (ISI) & inter carrier interference (ICI) with certain
procedure. Therefore peak to average power ratio (PAPR) is the
basic problem with OFDM. However in this paper we proposed a
reduction procedure of the PAPR by using clipping and filtering.
Here we use a composed high pass , low pass & Chevyshev band
pass filter II after amplitude clipping to reduce the PAPR. The
performance of the system in terms of bit error rate (BER) and
symbol error rate (SER) is also investigated as a new filter based
clipping method is proposed. Our proposed clipping method with
and composed high pass the Chevyshev bandpass filter II in
PAPR performance of the system with a little compromise of
BER & SER showing the significant improvement in Quadrature
Amplitude Modulation (QAM). |
