The invention belongs to the technical field of communication systems, and particularly relates to a method and device for generating a low-PMEPR four-phase Z complementary sequence pair, and the method comprises the steps: taking an aperiodic binary Z complementary sequence pair as a seed pair, multiplying a value in the seed pair by-2, adding the product to 1, and dividing an obtained result into two parts; multiplying one part of one sequence of the seed pair by one coefficient to obtain a first multiplication, multiplying the other part of one sequence of the seed pair by the other coefficient to obtain a second multiplication, and similarly, multiplying the other sequence to obtain a third multiplication and a fourth multiplication; adding the values in the first multiplication and the fourth multiplication to obtain a sequence c, adding the value in the third multiplication and the value in the second multiplication to obtain a sequence d, and obtaining an aperiodic four-phase Z complementary sequence p
