Performance Evaluation of Different Equalization Techniques for QAM in Wireless Communication | Original Article

ABSTRACT:

Due to the distortive character of the propagation environment and High bit data rate transmission over wireless channel makes the channel response extend over more than one symbol period transmitted data symbols will spread out in time and will interfere with each other, a phenomenon called Inter Symbol Interference (ISI). This is undesirable and makes the recovery of signal difficult. Equalization is method which is commonly employed to fight with ISI. In this paper different equalizer has been analyzed and compared for 2x2 MIMO channel.
