Performance Analysis of MIMO-OFDM with Doubly Selective Zero Forcing Equalizer Technique
Owk Srinivasulu, P. Rajesh Kumar
Abstract
Multiple input multiple output (MIMO) is a technology that combines multiple antennas and
orthogonal frequency division multiplexing (OFDM) modulation to increase the data rate and
spectral efficiency of wireless communication systems. One of the key issues with MIMO-OFDM
systems is the equalization problems, which are caused due to multiple antennas and subcarriers.To
address equalization issues, the doubly selective zero forcing (DSZF) equalization is proposed for
MIMO-OFDM systems.
Keywords
