Impact of Waveforms on Frequency Measurement Performance for Digital Channelized Receivers

摘要

摘要: 对于典型的数字信道化接收机之后级联相位差分法测频的处理架构，现有的测频精度表达式未考虑波形复包络对测量精度的影响。该文针对这一问题，推导了考虑波形复包络影响的新的测频精度表达式，并进行了仿真。仿真分析的结果与推导的精度表达式一致，表明改进的测频精度表达式能够有效反映信号波形对测频性能的影响。

Abstract: For a classical architecture consisting of a digital channelized receiver followed by frequency measurement using phase difference, the existing precision equation of frequency measurement does not consider the impact of waveform complex envelop on measurement performance. A new precision equation of frequency measurement considering the impact mentioned above is derived in this paper. The consistency of analytical results by the proposed precision equation with simulation results is verified. The simulation results indicate that the proposed equation can exhibit the impact of waveform on frequency measurement performance.
