Phase Noise and TD-SCDMA UE Receiver


摘要 : Four significant issues impact TD-SCDMA receivers: Phase noise, Noise figure, I/Q phase imbalance and power supply noise. Error vector magnitude is used to specify describe the influence of these factors on the radio receiver. Equations are given to estimate the impact of power supply noise, I/Q balance and LO phase noise.
