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×n_i×W channel configurations, wherein m is the number of receive antennas used to receive the packets, n_i 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 qn_i for all i.
