Partial transmit sequences (PTS) search complexity increases exponentially with the number of subblocks. To solve this problem, a novel immune quantum evolutionary PTS scheme is proposed to reduce computational complexity and improve PAPR performance. In this scheme, a Q-gate is introduced to drive the individuals toward better solutions, the evolutionary mechanism restrains degeneracy and increases the fitness of population, and a specially hexagonal constellation is used to eliminate side information. Simulation results indicate that the conventional PTS is more complicated than the proposed strategy, and that the proposal shows better performance without additional transmit sideband information than similar other solutions.
