发明名称 Compensation of the IQ phase asymmetry in quadrature modulation and demodulation methods
摘要 A simplified compensation matrix is set up for the compensation of phase errors between the I and the Q component in data transmission systems with quadrature modulation or demodulation. This simplified compensation matrix permits a previously determined phase error Deltaphi to be used as the basis for replacing two of the multipliers required in the conventional circuit configurations by relatively simple shift registers (4, 5) for a multiplication by 1 or by a constant.
