| Summary: | 碩士 === 大同大學 === 通訊工程研究所 === 95 === The modern digital communications are more and more enhances to high
efficiency transmission request, therefore to find a way to enhances data
transmission efficiency is popular subject. A communications signal
transmission over wireless channels, that in practice has suffers much
interference and noise influence. Especially, the practice channel is time
variance, which have different channel characteristic at different time. This
thesis mainly to proof that we can enhance the transmission efficiency by
change pilot pattern alignment at same pilot density condition, and to verify
the pilot pattern arrangement in diamond shape have highest transmission
efficiency then any other, by simulation manner.
