  • Extrapolating channel state information (“CSI”) estimates from multiple packets sent over different frequency channels to generate a combined CSI estimate for a MIMO-OFDM system
    Patent number: 9143218
    Abstract: 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.

  • Extrapolating Channel State Information ("CSI") Estimates From Multiple Packets Sent Over Different Antennas to Generate a Combined CSI Estimate for a MIMO-OFDM System
    Publication number: 20140294108
    Abstract: 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.
