A calibration apparatus and method in a communication system are provided. In the apparatus and method, baseband reference signals are generated for signal transmission paths, upconverted to RF signals, and downconverted to a baseband signal after coupling and combining, and transmission calibration vectors are acquired using the baseband signal, and a reference signal is generated, upconverted to an RF signal, distributed to signal reception paths, coupled, and downconverted to baseband signals, and reception calibration vectors are acquired using the baseband signals. Accordingly, the apparatus and method perform calibration without the need for using additional Tx and Rx hardware in a communication system which minimizes system complexity. |
