Abstract
An antenna switching apparatus based on spatial modulation includes a plurality of antennas; a control signal generator configured to generate a plurality of switching control signals; and a plurality of switches configured to switch on to apply a transmission signal to the respective antennas according to the respective switching control signals. Further, the antenna switching apparatus includes a delay analyzer configured to receive the transmission signal output from each of the plurality of switches to calculate delay information for synchronizing the switching control signals applied to the respective switches; and a delay adjuster configured to synchronize the switching control signals to apply the synchronized switching control signals to the respective switches according to the calculated delay information.
