| Abstract: | This article theoretically analyze the possibility of the mixing of added signals and received signals, when additional alternating signals are added by GMR apparatus in wireless communication system. The theory is also verified experimentally. GMR apparatus has good ability in working in high frequency, increasing the sensibility of detection and flexibility of design. It widely apply to the low-field magnetic sensing and wireless communication. |
