Abstract

A Rayleigh channel evaluation method includes the following steps: (1) an upper computer configures initial parameters required for a Rayleigh channel, packages the initial parameters into a first data packet, and transmits the first data packet to a channel simulator; (2) the channel simulator receives the first data packet transmitted from the upper computer, and then generates a corresponding Rayleigh channel fading sequence, packages the Rayleigh channel fading sequence into a second data packet, and transmits the second data packet to the upper computer; and (3) the upper computer receives the second data packet from the channel simulator, obtains fading sequence data, and then performs data analysis. According to the method disclosed by the invention, whether a fading channel is theRayleigh channel can be scientifically and effectively evaluated.

Description

technical field

[0001] The invention relates to the field of wireless channels, in particular to a Rayleigh channel evaluation method. Background technique

[0002] The classical Rayleigh channel model describes the state of the mobile wireless communication channel in the urban environment without a direct path, and is the most basic channel model of the wireless channel. The probability density of the envelope of the channel model obeys the Rayleigh distribution, the phase angle obeys the uniform distribution, and the Doppler power spectrum is a classic Jakes spectrum (U-shaped spectrum). In general, it is intuitively judged whether a channel fading sequence obeys the Rayleigh distribution by drawing the envelope probability density distribution diagram, phase angle distribution diagram and Doppler power spectrum. The results are not accurate enough to be convincing. Contents of the invention
