Abstract

The invention discloses a lognormal channel model verification system, comprising a signal generator, a wireless channel simulator, a network analyzer, a channel estimation processor and a channel verification module. The signal generator, the wireless channel simulator, the network analyzer, the channel estimation processor and the channel verification module are unidirectionally connected in sequence. The signal generator is also directly and unidirectionally connected with the channel estimation processor. The signal generator, the wireless channel simulator, the network analyzer and the channel estimation processor are mainly used for acquiring channel data. The channel verification module is mainly used for verifying the acquired channel data. According to the system, the channel datagenerated by the channel simulator submits to lognormal distribution or not can be judged conveniently and simply, whether a lognormal channel simulator model is accurate or not is effectively verified, the foundation for the channel research such as channel estimation is laid, and the guarantee for a receiving end to extract sending data accurately and effectively is provided.

Description

technical field [0001] The invention relates to a method for verifying a wireless communication channel model, in particular to a lognormal channel model verifying system. Background technique [0002] Channel simulation is an important task in wireless communication. It is an important prerequisite to make an effective assessment of the wireless communication environment and ensure whether the receiving end can accurately demodulate the transmitted data, especially in some complex communication environments, such as missiles, satellites, etc. , unmanned aerial vehicle, spacecraft, sea surface, civil communication and other complex communication conditions, channel simulation is an indispensable link. In the lognormal channel simulation simulator, the correctness and accuracy of channel modeling are particularly important. In the traditional method, it is generally observed visually whether the simulated channel data obeys the logarithmic normal distribution, which has a la...
