Design and Analysis of a Magnetic Field Communication System Using a Giant Magneto-Impedance Sensor

Given the interest of researchers for wireless communications in electromagnetic (EM) shadow areas, a magnetic field communication has emerged to overcome RF challenges based on permeability characteristics. However, demerit short range. Considering this limitation, we have proposed GMI sensor-based receiver obtain immunity low-frequency noise and high sensitivity extension range previous studies. Further, paper designs system with including transmitter. Even though basic concept is taken from studies, study conducts different realization transmitter link. Besides, proposes experiment using verify applicability practical environment first time. Bit error rate (BER), spurious-free dynamic (SFDR), random are measured on-off keying (OOK) link analyze stability reliability system. The experimental verification analysis entail conditions distance channel medium mimic atmospheric, underwater, underground environments. A comprehensive design application show possibility realize improving EM areas.
