Transmitter and receiver capable of reducing in-phase/quadrature-phase (I/Q) mismatch and an adjusting method thereof |
摘要 |
An adjusting method for reducing in-phase/quadrature-phase (I/Q) mismatch in a transmitter includes the steps of: a) receiving a first in-phase signal and a first quadrature-phase signal; b) adjusting a set of parameters such that an extent of I/Q mismatch related to the first in-phase signal and the first quadrature-phase signal is reduced; c) receiving a second in-phase signal and a second quadrature-phase signal, the second in-phase signal differing from the first in-phase signal in one of frequency and phase; d) adjusting the set of parameters such that an extent of I/Q mismatch related to the second in-phase signal and the second quadrature-phase signal is reduced; and e) determining final values for the set of parameters based on adjustment results of steps b) and d) such that extents of I/Q mismatch related to different frequencies are reduced.
