High quality multirate data transmission is demanding greater speed and accuracy for reliable and accurate reception. Specially, increasing wireless multimedia applications are infusing high data requirements. Rapidly time varying multi-carrier, multi-user based MIMO channels due to high mobility have inevitably necessitated equalization for the availability of partial or no channel state information at the transmitter and/or receiver which fetch new problems. Additive White Gaussian Noise (AWGN) encapsulates continuous uniform spectrum for the transmitted signal continuously in every channel.
