Extrapolating Channel State Information ("CSI") Estimates From Multiple Packets Sent Over Different Antennas to Generate a Combined CSI Estimate for a MIMO-OFDM System |
| 摘要 |
A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different antennas to generate a combined CSI estimate for a MIMO-OFDM system is disclosed. Packets are received on m×ni×W channel configurations, wherein m is the number of receive antennas used to receive the packets, ni is the number of transmit antennas used to transmit the packet indexed with i, and W is the number of OFDM channels 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×q×W channel configuration, wherein q>ni for all i. |

1. A method for extrapolating channel state information (“CSI”) estimates from multiple packets sent over different antennas to generate a combined CSI estimate for a MIMO-OFDM system, the method comprising:
receiving packets on m×ni×W channel configurations, wherein m is a number of receive antennas used to receive the packets, ni is a number of transmit antennas used to transmit a packet indexed with i, and W is a number of OFDM channels in the MIMO-OFDM system; generating CSI estimates for the received packets; and extrapolating the CSI estimates for the received packets to generate a combined CSI estimate for an m×q×W channel configuration, wherein q>ni for all i. |
