Problems solved by technology

[0003] However, the problem with wireless systems is that the characteristics of the wireless channel are that it changes rapidly as a function of time, and the attenuation and impulse response of the wireless channel vary in a large phase and amplitude range, even thousands of times per second
This method has certain problems: it cannot generate an accurate, timely, wid

Abstract

The invention discloses a wideband wireless channel simulator and a relative method, wherein the device comprises at least one signal channel, a computer controller, a computer, and a channel data exchanger. The signal channel receives and sends radio signal, the computer controller receives and buffers the channel parameter and control command generated by the computer, and transfers data to each signal channel, the computer bears an operation module simulated by the wideband wireless channel, while the operation module generates channel data and communicates with the computer controller, and the channel data exchanger exchanges data between signal channels. The invention can realize quick and accurate simulation of wideband channel, particularly for simulating the condition which uses antennas to send and/or receive signal transmitted in wireless channel. The inventive device has simple structure and easy application.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for simulating a radio channel and a channel simulating device for implementing the method. Background technique [0002] Wireless communication is an important branch of the communication field. With the improvement of digital signal processing capabilities, digital wireless communication has gradually become the mainstream of wireless communication. One of the important goals of digital wireless communication system design is to have a strong anti-jamming capability. Usually, designers need to virtualize various interferences that may exist in wireless channels (such as multipath, noise, co-frequency signals, etc.) The performance of communication equipment often requires repeated experiments in the actual communication environment, which will consume a lot of manpower and material resources. In order to shorten the development cycle, save development costs, and...
