A correlation OPTS algorithm for reducing peak to average power ratio of FBMC-OQAM systems
文献摘要：
A correlation overlapping partial transmit sequence(C-OPTS)algorithm is proposed to solve the issue of high complexity of overlapping partial transmit sequence(OPTS)algorithm in suppress-ing the peak to average power ratio(PAPR)of filter bank multicarrier-offset quadrature amplitude modulation(FBMC-OQAM)signals.The V subblocks in partial transmit sequence(PTS)are re-grouped into U combinations according to the correlation coefficient ρ,and overlapping subblocks are allowed between adjacent groups.The search starts from the first group and sets the phase factors of the subsequent groups to 1.When the phase factors of the non-overlapping subblocks in the first group are determined,the subsequent groups are searched in turn to determine their respective phase factors.Starting from the second data block,the data overlapped with it should be taken into ac-count when determining its optimal phase factor vector.Theoretical analysis and simulation results indicate that compared with the OPTS algorithm,the proposed algorithm can significantly reduce the computational complexity at the cost of slight deterioration of PAPR performance.Meanwhile,com-pared with the even-odd iterative double-layers OPTS(ID-OPTS)algorithm,it can further reduce the complexity and obtain a better PAPR suppression effect.
