Description: 2. For the doppler spectrum of wireless channels, please answer the following questions:
(1) in some wireless channels, doppler frequency shift can cause the aliasing of radio channel output signals. Describe the various reasons for the aliasing;
(2) the doppler spectrum in the wireless channel has a classic spectrum, please explain the mechanism that produced this spectral shape;
(3) please use the Simulink tool to write code (s-function mode) to generate a single path Rayleigh channel, with the doppler spectrum as the classical spectrum, where the moving speed is 120km/h. And please answer: it is possible to prove that the classical spectrum produced by your computer is correct.
-On the wireless channel of the Doppler spectrum, please answer the following questions: (1) In some radio channels, the Doppler frequency shift will cause the output signal of the wireless channel aliasing. Please describe the aliasing produced a variety of reasons (2) wireless channel in the Doppler spectrum has a classical spectrum (classic spectrum), please explain the mechanism of produce such spectral shape (3), please use the Simulink tool to write code ( S-Function mode), resulting in a single-path Rayleigh channel, the Doppler spectrum for the classical spectrum, including mobile rate of 120km/h. And requested the answer: that they used computer-generated classical spectrum is the right possible way.
