Next, the theoretical analysis method of code tracking performance in non-white interference environment is presented, which is followed by the discussion on the effects of interference frequency, bandwidth and receiver correlator spacing on code tracking accuracy. 给出了非白色干扰环境中的码跟踪精度理论评估方法,并讨论了干扰频点、干扰带宽及接收机相关器间隔对码跟踪精度的影响。
