scripts default iconLS & MMSE channel estimators for OFDM Publisher's description

LS & MMSE channel estimators for OFDM compares the performance of the LS and MMSE estimators for a 64 sub-carrier OFDM model

Here is a simulation based proof highlighting the superiority of the MMSE[Min Mean Sq Error] channel estimator over the LS[Least Sq] estimator.The two parameters of evaluation turn out to be, quite logically, the SER[Symbol Error Rate] and the Mean Square Error.The channel is assumed to be g(t)=delta(t-0.5 Ts) delta(t-3.5 Ts)

For more information on the theory and formulae used , please do refer to the paper On "Channel Estimation In OFDM systems" By Jan-Jaap van de Beek, Ove Edfors, Magnus Sandell, Sarah Kate wilson and Petr Ola Borjesson In proceedings Of VTC'95 Vol 2 pg.815-819.The two sub folders contain the code for the simulations related to the two parameters , i.e SER and MSE..
