dct-precoded-SLM-method-for-PAPR-reduction
dct precoded SLM method for PAPR reduction
High Peak to Average Power Ratio (PAPR) is still a
most important challenge in Orthogonal Frequency Division
Multiplexing (OFDM) system. In this paper, we propose a
Discrete Cosine Transform (DCT) precoding based SLM
technique for PAPR reduction in OFDM systems. This
technique is based on precoding the constellation symbols with
DCT precoder after the multiplication of phase rotation factor
and before the Inverse Fast Fourier Transform (IFFT) in
SLM-OFDM System.

SAX
Keogh的SAX聚集近似算法,首先采用PAA分段,然后正态化序列,在对应表上查询符号表示,这是一个很经典的时间序列表示方法(Keogh' s SAX gathered approximation algorithm, the first use PAA segment, then normal sequence, query on the corresponding symbol table indicates, this is a classic representation of the time series)
