<p><P>PROBLEM TO BE SOLVED: To provide a technology for achieving a MIMO UWB channel estimation support using a more efficient transmission system than that achieved in the IEEE802.11n system. <P>SOLUTION: A wireless MIMO communications network establishes channel estimation by means of a channel estimation sequence utilizing band hopping in the conventional manner from a first antenna. This channel estimation sequence can then be detected by legacy SISO devices. A further channel estimation sequence is concurrently transmitted from one or more further antennas, the further channel estimation sequence using a band hopping sequence complementary with the band hopping sequences so as to avoid collision therewith. This latter channel estimation sequence can thus be detected by cooperating MIMO receiving equipment to provide opportunities for channel estimation. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
