摘要： The present invention provides a method and a device for using one multiplier to implement multiplication of complex numbers. The method comprises: receiving a first complex number signal a+ci and a second complex number signal b+di, the first complex number signal and the second complex number signal being both digital communication signals; performing shift processing according to a first real part a and a first imaginary part c of the first complex number signal to acquire a first transformed value s, and performing shift processing according to a second real part b and a second imaginary part d of the second complex number signal to acquire a second transformed value t; according to the first transformed value s and the second transformed value t, performing calculation by using a multiplier to acquire a first reference value w1=st; and acquiring the real part and the imaginary part of the product of the first complex number and the second complex number according to the first reference value w1. The present invention further provides a corresponding device. The technical solutions of the present invention can overcome the disadvantage in the prior art that the utilization ratio of the multiplier is low.
