摘要
An apparatus and method for correcting phase and amplitude variations of a data signal caused by a non-linear system in a multi-antenna communication system. A BS adds a reference signal with a power level less than the power of the data signal to the data signal and accumulates the response of the non-linear system to the sum signal, estimates the variations in the phase and amplitude of the data signal, and calibrates the data signal using the estimate.
