METHOD AND APPARATUS TO IMPROVE PERFORMANCE IN A MULTICARRIER MIMO CHANNEL USING THE HADAMARD TRANSFORM |
| 摘要 |
<p>The Hadamard transform is used to spread data within data blocks in a multicarrier MIMO system, before transmission. In this manner, the negative effects caused by the clustering of bad subcarriers (i.e., subcarriers having a low transmission coefficient due to fading) may be reduced. In at least one embodiment, a MAP-type detection scheme is used in the receiver to extract bit reliabilities from the received signals.</p> |
