  • Abstract
    In the QPSK modulation and demodulation process, the signal will be affected by some non-ideal factors, in this paper, these non-ideal factors were analyzed. This paper considers the magnitude imbalance, phase imbalance and phase noise factors. We will study the QPSK constellation to analysis the amplitude imbalance and phase imbalance. About the phase noise we will consider the factors that affect the error rate of QPSK.
