摘要：
A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different channels to generate a combined CSI estimate for a MIMO-OFDM system is disclosed. Packets are received on an m×n×Wi channel configuration, wherein m is the number of receive antennas used to receive the packets, n is the number of transmit antennas used to transmit the packets, and Wi is the number of OFDM channels for a packet i in the MIMO-OFDM system. CSI estimates are generated for the received packets and the CSI estimates are extrapolated to generate a combined CSI estimate for an m×n×R channel configuration, wherein R>Wi.
