DFT Based MMSE Equaliser in MIMO-OFDM

MIMO-OFDM is considered as a fast growing technology now days. OFDM is a multi carrier modulation technique in which the carriers are Orthogonal to each others as a result of which it provides high bandwidth efficiency and multiple carriers share the data among themselves. During the research equalizer is always a matter of strategies. When a signal is transmitted over a radio channel, it is subject to reflection, refraction and diffraction and also the type of modulation technique selected at transmitter. In this paper Bit Error Rate performance of OFDM under Rayleigh fading channel is analyzed, and compared with Additive White Gaussian Noise Channel.
