Investigation of Peak to Average Power Ratio and its depreciation in OFDM based Low Power Digital Communication Systems

In a typical digital system implemented using Orthogonal Frequency Division Multiplexing (OFDM) communication modules, the main defensive component which affects the efficiency of digital data transmission is Peak to Average Power Ratio (PAPR) and it happens in the network, because of the use of higher order linear amplifiers. The proposed method in the article emphasis on the repeated based algorithm to minimize the PAPR in low power digital communication system based OFDM network by a asymmetrical depreciation or without the loss of data symbols in bit or code rate to satisfy very minimum range of Signal to Noise Ratios (SNR). Minimum range of PAPR results the communication system to function factor of 3-3.5 dB and corresponding clipping probability of 〖10〗

(-2), and with the comparison, with 5-5.5 dB equivalent to 〖10〗 ^(-4) to 〖10〗 ^(-5) resulting in.
