Raytracing channel and showProfile

13 次查看(过去 30 天)
Hello everyone, i have one question about the showProfile command. I study an urban enviroment with raytracing propagation model, using the channel = comm.RayTracingChannel(rays, tx, rx) object. I obtain the channel, and with these i can found the channel impulse response if i dont use any input:
CIR = channel( )
After i use the showProfile(channel) and i plot the power delay profile. Can i obtain the same plot using the sample from the CIR? Because i want to save the magnitude of every tap from the power delay profile, but with the showProfile command is not possible so i have to recreate those from myself.

Hi Nicolas, To extract the power delay profile from the channel impulse response obtained using the showProfile command in Matlab, you can recreate the power delay profile from the channel impulse response (CIR) data. The showProfile command visualizes the power delay profile but does not provide direct access to the individual tap magnitudes.
You can extract the tap magnitudes from the CIR data by processing the impulse response. Each tap in the CIR corresponds to a delay in the power delay profile. By analyzing the CIR data, you can identify the magnitudes of each tap and recreate the power delay profile accordingly. This process allows you to save the magnitude of every tap from the power delay profile for further analysis or processing.

thank you Umar, but the power delay profile it is not the square module of the CIR? Because i tried to compute it in this way but it doesnt match with the showProfile function
