Bias analysis of a gain/phase/DC-offset estimation technique for direct frequency conversion modulators

Abstract

This paper studies a least-square-based technique for compensation of gain and phase imbalances and DC-offsets in a direct frequency conversion quadrature modulator. The technique requires the instantaneous power measurement at the transmitter to calculate the gain/phase/DC-offset compensation coefficients. The biases of the estimated coefficients are… (More)
