METHOD AND APPARATUS FOR CALCULATING LLR BY USING CHANNEL INFORMATION IN FMBC SYSTEM FMBC

摘要

Disclosed are a method and apparatus for calculating LLR by using channel information in an FMBC system. The method according to the present invention comprises the steps of: (a) estimating a channel by using a reception signal; (b) estimating a conjugate channel of the estimated channel; (c) applying the estimated conjugate channel to the reception signal; (d) selecting only a real number component from the reception signal applied with the conjugate channel; and (e) calculating LLR by using the real number component selected in the step (d). According to an embodiment of the present invention, it is possible to calculate LLR while maintaining a channel gain with respect to a transmission signal which is filtered by an FMBC system.;COPYRIGHT KIPO 2015
