摘要： Provided is a method for processing received signal by applying channel status information based on OFDM. The method applies CSI to a soft-decided signal and thus can more enhance performance than a method applied to a typical decoder even without using an additional memory and the increase of a clock speed. The method appropriately perform adjustment suitable for a soft-decided and received signal in applying pre-estimated CSI to a decoder, thereby more enhancing performance and enabling adaptive application based on the change of a channel status. The method includes performing a first operation of calculating a new second Channel Status Information (CSI) value CSINEW for enhancing reliability of a received first CSI CSIRECEIVED, and applying a weight value to the calculated new second CSI value CSINEW to calculate a third CSI value CSIWEIGHTED; performing a second operation of applying the third CSI value CSIWEIGHTED having the weight value to a first soft-decision value SSOFTDECISION of an actually-received signal to calculate a second soft-decision value SSOFTDECISION+CSI adjusted; and performing a third operation of restrictedly controlling an output range of the calculated second soft-decision value SSOFTDECISION+CSI to finally obtain a third soft-decision value SSOFTDECISION+CSI—Bounded calculated.
