| Abstract: | Focusing on the problem of the peak-to-average power ratio (PAPR) of OFDM technique, the methods for reducing the PAPR of 16QAM-OFDM signal using Golay complementary sequence (GCS) are investigated, their properties, namely the maximum PAPR value, set size of 16QAM sequences and code rate, are analyzed and compared in detail, and the encoding and decoding algorithms and error control capabilities are discussed in brief. Analysis results suggest that these methods have different predetermined application conditions for different system design requirements. |
