Abstract

The invention discloses a Gaussian channel simulation method and a Gaussian channel simulation system. The Gaussian channel simulation method comprises the steps of (1) generating a communication signal s(t); (2) generating a Gaussian channel; and (3) simulating the Gaussian channel, to be specific, enabling the communication signal s(t) to pass through the Gaussian channel to obtain an output signal, analyzing the output signal and verifying the accuracy of the Gaussian channel.

Description

technical field [0001] The invention relates to a Gaussian channel simulation method and a simulation system thereof. Background technique [0002] The Rayleigh channel model describes the multipath effect and Doppler effect of a wireless channel in a small scale, and is the basic model of a wireless communication channel. Under the Rayleigh model, the statistical characteristics of the channel amplitude obey the Rayleigh distribution, the phase angle statistics obey the uniform distribution, and its Doppler power spectrum is a classic Jakes power density function. However, this channel model can only reflect the mobile wireless channel model in the environment without a direct path, and cannot describe the gain change caused by antenna swing in mobile communication. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned background technology and provide a Gaussian channel simu...
