Abstract

In this paper we proposed a new peaktoaverage power reduction PAPR algorithm of orthogonal frequency division multiplexing OFDM system using block coding scheme and discrete cosine transform DCT We are using DCT to concentrate the energy of the original signal into a few coefficients After the DCT data were fed into the IDFT the output of signal of OFDM appeared to have uniform distribution With the newly proposed schemes that we founded those three important properties the first property is the PAPR used be reduced by 94419 dB for BPSK mapper The second property is the OFDM signals have capability of noise immunity and of error correction And the third property is the effect of PAPR reduced can be implement by cascaded different method
