PAPR reduction using Huffman coding combined with clipping and filtering for OFDM transmitter
Orthogonal Frequency Division Multiplexing (OFDM) technique has some drawbacks. One
of them is high peak-to-average power ratio (PAPR). This paper proposes a technique to
reduce the PAPR using Huffman coding combined with clipping and filtering (CF). The
simulation results show that using the combination of Huffman and CF methods is more
effective than using each method separately. By using 52 subcarriers and QPSK modulation,
about 7 dB PAPR reduction is achieved.
