摘要
基于2FSK信号解调的原理,加入延迟、多径效应、AWGN条件以模拟现实传输环境,建立了用包络检波实现2FSK信号解调的simulink仿真模型,并在simulink环境下进行仿真分析。重点论述了采用数字谐振器实现信号包络检波和定时提取的方案。
Based on 2FSK demodulation principle, with envelope detection method, a simulink model under the condition of delay, multipath effect and AWGN which simulate reality transmission environment has been established and the analysis is made in simulink software environment. Mainly discusses using the digital resonator to realize the extraction of signal enveloping and timing.
