Title:
直交周波数分割多重方式によるチャネル状態情報を適用して受信信号を処理する受信信号処理方法
Document Type and Number:
Japanese Patent JP2013501395
Kind Code:
A
Abstract:
Provided is a method for processing received signal by applying channel status information based on OFDM. The method applies CSI to a soft-decision value of the received 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 system 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 CSI NEW for enhancing reliability of a received first CSI CSI RECEIVED , and applying a weight value to the calculated new second CSI value CSI NEW to calculate a third CSI value CSI WEIGHTED ; performing a second operation of applying the third CSI value CSI WEIGHTED having the weight value to a first soft-decision value S SOFTDECISION of an actually-received signal to calculate a second soft-decision value S SOFTDECISION+CSI adjusted; and performing a third operation of restrictedly controlling an output range of the calculated second soft-decision value S SOFTDECISION+CSI to finally obtain a third soft-decision value S SOFTDECISION+CSI _ Bounded calculated.
