Investigate of training based channel estimation for a MIMO-OFDM system over different modulation technique / Nadiatul Akmal Kamaralzaman

Orthogonal Frequency Division Multiplexing (OFDM) in communications systems combine with Multiple-Input Multiple-Output (MIMO) can improve capacity and achieve high data rate. In OFDM communications systems, the system performance will be cause to Inter-symbol Interference (ISI). Therefore, the pilo...
