Paper Title - PAPR Reduction Techniques Focusing On Harmony Search Algorithm
The Orthogonal Frequency Division Multiplexing (OFDM) is one of the finest modulation techniques used
now-a-days. With high spectral efficiency it has a severe drawback of having high Peak-to-Average-Power (PAPR).This paper
focuses on the threshold-based piecewise companding technique and harmony search algorithm technique to reduce the PAPR.
The threshold-based-piecewise companding technique obtains reduction in PAPR with low bit error rate (BER) loss, while,
harmony search algorithm obtains reduction in PAPR with reduced computational complexity.
