Hi dear John!
You have not shared a MATLAB code for the DOA and DOD estimation of a channel per user in a MU-MIMO system? Can you upload it in near future as I am stuck in it? Regards,

Hello, I want to simulate probability of error for the BPSK signal in the presence of frequency offset and then compare it with theory.
Can you please help me model the simulation with frequency offset?

Please comment on the relevant post so I can help you with this. One point I would like to make is that most of my simulations are in baseband whereas for frequency offset simulation you would have to work in the passband.

Thank you for your reply. Yes, the frequency offset is there because of the oscillator mismatch, i.e., at passband, so please help me with simulation and theory results in the presence of synchronization error.

Actually I have to do this for MSK signals. But If you first provide for the BPSK signal is also ok for me. I will follow the same procedure for MSK.

Hi, I am trying to write a PYTHON code BER for BPSK modulation in 3 tap ISI
channel and Zero Forcing equalization with 3/5/7/9 tap with its BER but couldnt figure it out correctly.Kindly help me.

I am trying to measure the k Rician factor with the moment’s estimator and after creating the fading envelope for EVA, which has 9 taps, I have a matrix of 9xNsamples.

Do I have to estimate the k factor for each path or there is a way to estimate the factor in the whole channel?

The Rician K-factor is defined as the ratio of signal power in dominant component over the (local-mean) scattered power. Rayleigh fading is recovered for K=0 (-infinity dB). So for Rayleigh Fading Simulator that we have discussed the K-factor should be zero unless you artificially add a strong dominant component.

Many thanks for the effort and time expended to assist solar Power installers with your software that assist us calculate panels, batteries and other accessories needed to install solar power system in a house, office and so on.

I wish to suggest that you redevelop the software again if that is possible and add the following please. Size of inverter required, days of autonomy in case of genset failure or days of continuing rains. Again, we installers especially those in Africa shall appreciate in your organisation can provide another software for health facilities equipment n addition to those items for house hold already provided. This would assist installers properly size solar power system for hospitals, clinics, etc.
Once again thank you for your support and interest to assist us promote solar power system in Africa especially in Ghana.

I am currently working on my master’s thesis and I can not make programming a channel variation in time and wanted to see if you can help me find the programming for that channel will be helpful for me.

hi, ı want to make oqpsk however , ı could not make it exactly. Especially, demodulation part was not done. could you help for this subject? how can ı do this

Hello, have you done any work on basestation location optimisation in wireless network for maximum coverage(in matlab)? if u have any codes or any idea about this, it will be much appreciated. thanks(feel free to email me)

hi,the link you sent not help me very well ,I want to send my program to your email if you could help me to give good results but i do not know yours email so send to me ,please to up my program please help me ,rana

Dear John I tried to search the reference for the following:

Definition: The system is called bi-static MIMO radar if the (Tx) array is kept far from the (Rx) array.

Question: But what is the limit i.e., how far away and where is the reference?

Can you help me in this regard please?

I want to implement the SBR(shooting and bouncing ray ) algorithm in outdoor environment. Are there any suitable materials ,books or code?

Hello and do not be bored – I need a pathloss installation tutorial can you help

Look at the Android app, maybe it is helpful.

Please share Python program for Hamming code, AWGN performance, BER and Er.

How to create encoder to detect channel at decoder using Python.

Please share MATLAB code for what you want to do and I will convert it into Python.

Kindly assist me with OFDM simulink model.

Thanx, u guys are the best. How do I get a simulink model of OFDM, PLS kindly send it to my mail.

I have MIMO code and OFDM code but its not all integrated. You can have a look around the site to see whats of use to you!

Do you have a executable matlab codes for MIMO – LTE ? If yes can you send to me? I need it desperately….
