modem.qammod is obsolete now.

'''modObj = modem.qammod(M);
demodObj = modem.qamdemod(M);'''
These two lines sould be commented out.
This line '''XD = modulate(modObj,X)/sqrt(10); % normalizing symbol power''' should be replaced by
'''XD = qammod(X,M)/sqrt(10);'''

please could you send to me a Matlab code for MIMO-OFDM LS and MMSE channel estimation.my email : Tarteel168@hotmail.com

Abdelwahab Afifi

there are some mistakes in the code:
1- you have repeated the same TDMSE_LMMSE in the following commands;
TD_ChEstMMSE(ii)=TDMSE_LMMSE/MC;
TDD_ChEstMMSE(ii)=TDMSE_LMMSE/MC;
2- there is no difference between TDDMSE_LMMSE&TDQabsMSE_LMMSE because you use the same qhat in both cases

Hello does anyone know about intercarrier interference mitigation with 8psk modulation. For channel estimation it needs to do interpolation. Cab you contact with me ekinsami@gmail.com

Hello, Sir, I have been looking at you codes as the reference I am having some problem on the parameter which was used I hope I could get some help from you understanding your code.
MC=1500
and
ChEstLS(ii) = ChMSE_LS/MC;
ChEstMMSE(ii)=ChMSE_LMMSE/MC;
TD_ChEstMMSE(ii)=TDMSE_LMMSE/MC;
TDD_ChEstMMSE(ii)=TDMSE_LMMSE/MC;
TDQabs_ChEstMMSE(ii)=TDQabsMSE_LMMSE/MC;
use of these .
my email is (rnr.atul@outlook.com) hoping for your response.
Thank you

Sir, it would be great if i could get any information about the code on CHANNEL ESTIMATION IN MIMO using a technique LSE, MMSE, MSE, LMMSE USING PILOT CHANNEL ESTIMATION. (rnr.atul@outlook.com)
