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.
