Orthogonal Frequency Division Multiplexing (OFDM) has great demand in wideband digital communication. It encodes the data on multiple carrier frequencies. Its application areas are digital audio broadcasting and high definition television, wireless network, 4G mobile communications. Due to its great advantages like it provides high spectral efficiency, remove inter symbol interference, reduced nonlinear distortion it is widely used for communication purpose. Major problem of this scheme is high Peak to Average Power Ratio (PAPR). To overcome this problem i.e. PAPR, here in this paper we figure out different reduction techniques, there pros and cons and also find Selective Mapping (SLM) is better technique due to its several advantages with reduced PAPR and better Bit Error Rate (BER) which is discussed further in this paper.
Keywords: Hybrid Techniques, OFDM, PAPR, Precoding Techniques, Reduction Techniques
