Abstract: To solve the problem of high computational complexity in the process of suppressing PAPR of filter bank multicarrier-offset quadrature amplitude modulation(FBMC-OQAM)applying the algorithm of overlapping partial transmit sequence(OPTS), a method of improved parallel tabu search overlapping partial transmit sequence algorithm(parallel-TS-OPTS)was proposed,which further increased the probability of finding the best phase factor vector by the operation of genetic crossover of the optimal solution of h-path traditional tabu search algorithm to optimize its initial solution. Theoretical analysis and simulation results showed that the proposed algorithm could not only achieve a PAPR suppression effect close to that of OPTS algorithm, but also significantly reduced the computational complexity of the algorithm, and further improved the robustness of FBMC-OQAM system applied in 5G scenarios.

Key words: filter bank multicarrier, PAPR, partial transmit sequence, tabu search algorithm, genetic cross operation
