Study and Performance Analysis of a General MIMO-OFDM System for Next Generation Communication Systems

MIMO is an acronym for 'Multiple Input Multiple Output'. In this technology, more than one antennas are mounted at each end to improve the performance of a communication system. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a Multiple-Input Multiple-Output (MIMO) OFDM system. This paper discusses the basic introduction to a general MIMO-OFDM system including the block diagram, governing equation, relevant designing parameters and brief analysis of system performance parameters.
