摘要
利用复基带信号模型推导了在串行干扰抵消中 ,PSK干扰信号参数估计误差 (包括符号定时误差、载波相位误差、幅度估计误差、误码率 )及信道估计误差与干扰抑制比的关系 ,通过仿真验证其可作为选择具体参数估计算法的重要依据。
Based on complex base-band signal model, the performance degradation in serial interference cancellation caused by imperfect parameters extraction of PSK interference signal (such as symbol timing error, carrier phase error, signal amplitude error, symbol error and channel estimation error, etc.) and channel are analyzed. The analysis results are verified by computer simulations.
