From computer simulations, we show that this unique pilot pattern is also suitable for channel estimation and would be able to achieve a good system performance for MIMO-OFDM systems. These examples do not provide information about the fragmentation mechanisms that cause these patterns. Consequently, we must deduce their meaning from the context. Infrared spectra may be obtained from samples in all phases (liquid, solid and gaseous). Dept. Most often this information is incomplete because the resolution is inadequate, or is restricted to 2-D, via some kind of micrograph, or is not available at all. $, ($0
