Abstract
Disclosed are a method and an apparatus for amplitude modulation of a spread signal that can increase a data transmission rate and frequency use efficiency by loading information on the amplitude of the spread signal used in digital communications. A method for amplitude modulation of a spread signal according to an exemplary embodiment of the present disclosure includes: receiving a first data signal; generating a spread signal by applying a spreading code to the first data signal; receiving a second data signal; and outputting the spread signal at an amplitude corresponding to a value of the second data signal.
