Hi all,
I need to calculate the pathloss exponent (n) using MMSE estimate. I have done some calculations and trying it in Matlab to find n. By theoretical calculations, i got n=4.4 but i dint get it while implementing in Matlab. please check Matlab code below which i have tried.
d=[100...
Hi all,
I'm trying to model my channel using auto regressive model. I have a doubt in that model. After finding the AR parameters using the yule walker equation, please tell me on how to find the poles from this parameters?. Can you also please suggest me some procedure on how to properly...
Hi all,
I'm measuring the frequency response and calculating the power delay profile. In between the transmitter and receiver, i kept the box with water(level-24cm). I'm measuring in indoor environment and also in Anechoic chamber. I calculated the rms delay spread for both cases. Indoor...
Thanks for your reply. Ya i'm expecting an envelope as you had shown. But i'm keeping the rectangular box in between the Tx and Rx, so due to channel in between the Tx and Rx should make the transmitting signal get distorted and it should undergo fade, rite?...In real time, while measuring a...
Hi,
I'm using R&S FSU spectrum analyzer, I want to get a proper received Envelope and from that i need to calculate the fading statistics. But while taking the measurements i'm getting the image which i have attached with this post.
I'm transmitting a sine wave from signal...
OK..But i have only spectrum analyzer. So after getting the received signal, is there any way to determine the fade?? In most of the paper they have used spectrum analyzer, but not described clearly about the measurements.
I need to find fade depth, level crossing rate and average fade duration from the received envelope. Can you please tell me the procedure to find it from spectrum analyzer, it would be helpful for me.
OK OK. I have attached a doc and in the table.1 they have calculated fading depth. Please see and tell whether they have calculated as you said. Please find doc attached.
OK OK...But the data set which we obtain from spectrum analyzer as said before should be converted to linear values and it should be normalized to its RMS value and it can be converted to db. After that as you said the largest signal magnitude is subtracted with smallest signal mag, Which will...
Ok ok. I'm transmitting the signal from signal generator and FREQ is 2.4GHz and level is 0dbm. I need to analyze the fade depth of the received signal envelope and need to determine level crossing rate from received signal envelope.
ya, i know in zero span mode, it is more like oscilloscope. I mean after taking the data set from spectrum analyzer and plotting the amplitude Vs time. Is the plot is said to be received Envelope(R) which is used to calculate the fade depth (R/Rrms)? or after taking data set should we have to do...
Hi,
I have to measure the fade depth from the received signal obtained from spectrum analyzer. The data set obtained from the spectrum analyzer is said to be a received envelope signal? I'm keeping it in zero span and measuring the signal. Please clarify my doubt.
Thank you,
Regards,
David.
