“…The proposed new Riemann matrix shows a near elimination of around 8 db to 8.5 db is obtained. In [7], it is stated that the Centering matrix shows the PAPR reduction more than the Riemann (which can also be seen in Figure 2). From this research work, it can be stated that the proposed new Riemann matrix performs even better than the Centering matrix.…”

“…The centering matrix is symmetric and idempotent, which when multiplied with a vector has the identical effect as subtracting the mean of the components of the vector from every component [7]. The structure of the centering matrix (Cn) is given by the relationship:…”

“…Thus, there can be many possible phase sequences. On the contrary, instead of generating a random phase sequences, various special matrices are suggested in the latest reference literature [5][6] [7]. The Hadamard and the Riemann matrices are preferred for the generation of the phase sequences.…”

“…Another matrix suggested recently is the Centering matrix. This matrix performs even better than the Riemann matrix [7]. In this experimentation, the combinations of the Centering matrix with the special matrices like the Hadamard and the Riemann are explored.…”

“…The error control coding or the channel coding can be an effective measure to protect the side information. In this experimentation, the side information is sent in the form of a row index or the row number of the phase sequence generator matrix, which provides the least PAPR for a particular OFDM symbol [7] [9]. The BCH coding is done on the set of the side information which is collected for all the corresponding OFDM symbols.…”

Orthogonal Frequency Division Multiplexing (OFDM) is a robust and effective multicarrier transmission technique for high speed communication in the wireless mobile environment and applications. A major challenging issue in the application of OFDM is its high peak to average ratio (PAPR). The Selective Mapping (SLM) is one of the promising techniques which offer a distortion less PAPR reduction at the cost of bandwidth efficiency and computational complexity. The rows of the Hadamard, Riemann and the Centering matrices are suggested to be used as the phase sequences in the literature. In this research work, the original SLM scheme is modified by using the new phase sequences, which are the combinations of the circulating matrix along with the Hadamard and the Riemann matrices. The simulation results show that the proposed phase sequences offer an improved PAPR reduction and thus outperform some of the previously proposed techniques.
