A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX

phase noise effect in matlab simulink

This Paper is concerned with the study of the performance of DPSK (differential phase shift keying) Modulation Technique using AWGN(Additive white gaussian noise) channel. The DPSK has remarkable features such as limited bandwidth and constant en

对二阶系统进行幅频和相频频率特性的获取，以及噪声干扰的添加，去除等。-Second-order system amplitude-frequency and phase characteristic frequencies of the acquisition, as well as noise adding, removing and so on.
