How can I get the impulse response about received signal power by using Winprop API

Kayiu Leung

Hello, everyone. Recently, I have been studying how to use the WinProp API, but I have encountered a problem. I found that the WinProp API cannot help me output impulse response data containing the received signal power. The channel impulse response it outputs is represented in field strength. How can I obtain channel impulse response data containing the received signal power like this ↓

I know there is a way I can save the impulse response values in ASCII-File by right clicking the impulse response window, so how can I get the multi-path Delay and Power while using API ? or is there any way I can get Delay and Signal Level of each ray while using API ?↓

Hi Kayiu,

If you do not manage to get the channel impulse response in dBm you can use and implement the following conversion formula after obtaining the results through the API:

Rx power [dBm] = e [dBuV/m] – 77.21 – 20*log(f/MHz)

This is a general formula (ignoring the Rx antenna gain, i.e. assuming isotropic receiving antenna).
