abstract = {This paper studies the impact of time-variation within a transmission block
on multiple-input multiple output (MIMO) OFDM, which is the chosen modulation strategy
of 4G wireless systems. We demonstrate how time-variation can lead to inter-carrier
interference, and give algorithms that can mitigate its effects. A central challenge is how to
estimate the channel, when it varies within a block. We devise pilot tone placement strategies that enable better channel estimation. We show that in time-varying channels it
may be better to group pilot tones together into clumps equispaced onto the FFT grid; this placement technique is in contrast to the common wisdom for time-invariant channels.},
