Impact of MIMO Pilot Sequence Length and Frame Length at Different Frequencies

The sensitivity of MIMO error performance to imperfect receiver channel state information is examined. Measurements made at three different UHF frequencies are used to show the effect of parameters such as training and frame lengths on error performance. The results show that the amount of training directly influences the supportable symbol rate and that the level of degradation in performance due to delay is highly dependent on frame length, frequency and channel geometry.
