Abstract

The invention discloses a SUZUKI fading channel simulation method and a SUZUKI fading channel simulation system. The simulation method includes steps: (1) generating a communication signal s (t); (2) generating a SUZUKI fading channel; (3) subjecting the SUZUKI fading channel to simulation, to be more specific, allowing the communication signal s (t) to pass through the SUZUKI fading channel to obtain an output signal, and analyzing the output signal to verify accuracy of the SUZUKI fading channel. The SUZUKI fading channel is a product of a Rayleigh channel and a shadow fading channel, the Rayleigh channel is used for describing small-scale fading, and the shadow fading channel is used for describing mesoscale fading, so that embodiment of both a small-scale fading process and a mesoscale fading can be realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a SUZUKI fading channel simulation method and a simulation system thereof. Background technique [0002] The traditional channel simulation method uses the Rayleigh channel model. 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 small-scale mobile wireless channel model, and cannot reflect the process of mesoscale fading (shadow fading process) in more detail. Contents of the invention [0003] The technical problem to be solved by the present in...
