Abstract: A method for converting source data to a channel-modulated signal having a plurality of pairs of in-phase (I) and quadrature-phase (Q) data in a mobile station, wherein the mobile station uses at least one channel, includes the steps of: a) encoding the source data to generate at least one data part and a control part; b) generating at least one spreading code to be allocated to the channel, wherein each spreading code is selected on the basis of a data rate of the data part and the control part and spreading codes are selected so that two consecutive pairs of the I and Q data are correspondent to two points located on same point or symmetrical with respect to a zero point on a phase domain; and c) spreading the control part and the data part by using the spreading code, to thereby generate the channel-modulated signal.

Abstract: Disclosed is a method of sensing illegal flight of a low-flying drone. Here, the method of sensing illegal flight includes: changing a direction of a beam on the basis of a preset period; and detecting an object by using the beam changed on the basis of the preset period. Here, the direction of the beam is changed on the basis of a first direction and a second direction. The first direction is changed on the basis of conversion of a center frequency, and the second direction is changed on the basis of a phase and a particular value.
