    Abstract: A spin-orbit torque (SOT) measuring apparatus includes a photoelastic modulator (PEM) configured to periodically modulate a polarization direction of linearly polarized incident light and emit a periodically modulated light, a first polarization rotator configured to rotate a polarization direction of the periodically modulated light, a voltage generator configured to generate an AC current to a sample to which light with the rotated polarization direction is to be emitted, a prism configured to split light reflected into first light and second light having different polarization directions, a balanced detector configured to output a signal corresponding to an intensity difference between the first light and the second light, a changing circuit configured to change a frequency component to the intensity difference, and an amplitude measurer configured to measure an amplitude of a frequency component corresponding to a modulation frequency of the PEM with the changed frequency component.

    Abstract: A signal transmitter and receiver are provided. The transmitter includes: a Multiple Input Multiple Output (MIMO) precoder configured to, in response to a first input signal and a second input signal, generate a first transmission signal and a second transmission signal by performing MIMO precoding by pre-phase shifting or pre-phase shifting/hopping the second input signal, and superposition encoding the first input signal and the pre-phase shifted or pre-phase shifted/hopped second input signal; and an Orthogonal Frequency Division Multiplexing (OFDM) modulator configured to OFDM modulate the first transmission signal and the second transmission signal.
