METHOD FOR CHANNEL STATE INFERENCE/PREDICTION AND ERROR RECOVERY IMPROVEMENT USING VARIABLE PARAMETERS, AND METHOD FOR DERIVING BER/PARAMETER ESTIMATION MODEL

摘要

A method for inferring and estimating a wireless channel state using an observation parameter and a method for inducing a bit error rate/parameter inference model are provided to improve the error recovery by inferring and estimating the bit error rate of a reception data packet by using an observation parameter. An observation parameter for estimating a channel state is determined from one data packet received through a wireless channel(400). A BER(Bit Error Rate) for the reception data packet based on the determined observation parameter is estimated(406). The estimated BER is fed back to a transmission side.
