The invention relates to the technical field of communication, and provides a method, a device, electronic equipment and a storage medium for determining simulation parameters of a filter. By obtaining the group delay of the channel to be simulated, i.e. the target group delay; then according to the target group delay, the frequency response function of the first filter is obtained, and the first filter represents an IIR filter for simulating the target group delay; Then, according to the frequency response function of the first filter, the simulation parameters of the second filter are obtained, and the second filter represents an FIR filter for simulating the target group delay. Based on the frequency response function of the IIR filter, the simulation parameters of the FIR filter are obtained, thereby overcoming the problems that the IIR filter cannot be operated in parallel and occupying a large amount of resources, and improving the accuracy of channel group delay simulation.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device, electronic equipment and storage medium for determining simulation parameters of a filter. Background technique [0002] In the process of high-speed data transmission in the communication system, the group delay of the channel will affect the data transmission and make the data distorted. In the prior art, the IIR filter is usually used to simulate the group delay. The IIR filter has a variety of structures, and the commonly used ones are direct type 1, direct type 2 and cascaded type, but no matter what structure it is, feedback buffer is required , not suitable for processing high-speed data. Contents of the invention [0003] In view of this, the object of the present invention is to provide a filter simulation parameter determination method, device, electronic equipment and storage medium. [0004] In order to achieve the above object, th...
