The effects of I/Q imbalance of the performances of QPSK in uncoded and coded schemes : imbalance detection and compensation techniques
Analogue implementations of quadrature modulation circuits are usually imperfect and suffer from several impairments. Among these impairments, the amplitude imbalance and phase imbalance are the major source of signal distortions especially for direct conversion schemes. The imperfection contributes...
