A transceiver device capable of calibration, and a calibration method used by the transceiver device. The transceiver device includes a reference transceiver, a plurality of remaining transceivers, and a plurality of transmission calibration paths connecting the remaining transceivers to the reference transceiver for transmission calibration of the remaining transceivers. An envelope detector included in the reference transceiver is shared with the remaining transceivers. When implementing a multiple input multiple output (MIMO) transceiver in a single chip, the chip size and manufacturing cost of the MIMO transceiver device can be substantially reduced.

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.
