  At this present scenario, the demand of the system capacity is very high in
wireless network. MIMO technology is used from the last decade to provide this
requirement for wireless network antenna technology. MIMO channels are mostly
used for advanced antenna array technology. But it is most important to control
the error rate with enhanced system capacity in MIMO for present-day
progressive wireless communication. This paper explores the frame error rate
with respect to different path gain of MIMO channel. This work has been done in
different fading scenario and produces a comparative analysis of MIMO on the
basis of those fading models in various conditions. Here, it is to be
considered that modulation technique as QPSK to observe these comparative
evaluations for different Doppler frequencies. From the comparative analysis,
minimum amount of frame error rate is viewed for Rician distribution at LOS
path Doppler shift of 0 Hz. At last, this work is concluded with a comparative
bit error rate study on the basis of singular parameters at different SNR
levels to produce the system performance for uncoded QPSK modulation.
