The economical PAPR minization scheme for combinative coding technique applied OFDM communication system
In this paper, we propose a new combinative scheme to combine with parity check and block coding methods for the reduction of the peak to average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) system. In the proposed schemes, the simulation results shown that Peak-to-Average Power Ratio (PAPR) can be reduced by 3.502 dB. The results of this mapped can be shown that PAPR is reduced. The principle of the scheme is illustrated with the specific example of an eight-carriers signal and its computer simulation results. All simulation results have compare with ideal channel case and AWGN case separately; both of cases are shown the PAPR reduced indeed.
