However, during the simulation process, we found that the existing simulation methods often use cumbersome parameter sequences or fixed frequency response curves to describe the target channel, which not only makes the simulation process more cumbersome, but also cannot meet the requirements of different frequency response requirements. Curve customization needs to complete the simulation of the power line channel

Embodiment Construction
[0013] The invention will be further described in detail below in conjunction with the drawings.
[0014] figure 1 The steps of a method for generating a power line channel by real-time simulation of a frequency response curve according to an embodiment of the present invention are schematically shown.
[0015] Such as figure 1 As shown, S01, the input window of the frequency response curve is built on the computer, that is, a frequency response coordinate interface is provided on the computer. The frequency response coordinate interface has an abscissa and ordinate respectively, which can be used by mouse or finger (with touch screen In the case of ), draw the frequency response curve that needs to be simulated on the coordinate interface. When the mouse or finger draws the frequency response curve on the coordinate interface, the background software will record the trace of the mouse or finger, and the drawn curve meets the frequency The mapping relationship between (abscissa) an...

The invention discloses a method for emulating and generating a power line channel in real time through a frequency response curve. The method includes the steps of providing a frequency response coordinate interface, drawing the frequency response curve on the coordinate interface, normalizing the frequency response curve into a frequency response characteristic array according to the frequency response coordinate system, conducting inverse Fourier transform on the frequency response characteristic array to obtain a filter theoretic parameter array, and substituting the filter theoretic parameter array into an emulation model to emulate the power line channel. Due to the fact that the frequency response curve can be drawn on the coordinate interface, the frequency response curve customizing mode is visual and flexible; due to the fact that the emulation process of the frequency response curve is integrally completed on the system, the emulation process of the power line channel is simplified, and the process of emulating and generating the power line channel in real time through the frequency response curve is higher in speed and lower in price.
Description
Technical field [0001] The invention relates to a method for generating a power line channel by real-time simulation of a frequency response curve. Background technique [0002] In the field of power line channel simulation, the way that the power line channel simulation system generates a certain characteristic channel is: use third-party tools (such as LabVIEW, VC, VB and other development environments with interface development functions.) to transform the frequency response curve into the simulation system. Identify the parameters, and then import the parameters into the simulation system to simulate the required channel. However, during the simulation process, we found that the existing simulation methods often use cumbersome parameter sequences or fixed frequency response curves for the description of the target channel, which not only caused the simulation process to be cumbersome, but also could not meet the requirements of different frequency responses. The curve needs ...
