ABSTRACT:
An apparatus and method for transmitting and receiving multiple signals inclusively in one channel are provided. The apparatus for transmitting multiple signals inclusively includes a single-sideband signal synthesis unit which synthesizes single-sideband signals having predetermined bands to generate an inclusive single-sideband signal which includes the bands of the single-sideband signals; a main modulation unit which modulates an inclusive single-sideband signal with a primary carrier frequency to generate an inclusive double-sideband signal where the primary carrier frequency is the center frequency; a main band pass filter which allows only any one single-sideband signal of an inclusive double-sideband signal to generate an inclusive single-sideband signal where a primary carrier frequency is an edge frequency of the inclusive band; and an inclusive single-sideband signal transmission unit which transmits an inclusive single-sideband signal. By transmitting and receiving multiple signals inclusively in one channel, the apparatus can efficiently process transmission and reception of multiple signals.
