DATA RECEPTION METHOD CAPABLE OF OBTAINING SIGNAL DETECTION PERFORMANCE SIMILAR TO A MAXIMUM LIKELIHOOD METHOD, AND A DEVICE THEREOF

摘要

PURPOSE: A data reception method and a device thereof are provided to reduce the complexity of a calculation by using a MIMO(Multi-Input Multi-Output) mode.;CONSTITUTION: A decomposition part(120) decomposes a channel estimated from received plurality of streams into a Q matrix and R matrix. A detection part(140) detects a first trim and the reference symbol of the first stream among the streams based on the R matrix. A candidate symbol detection part(150,155) detects the candidate symbols of the first stream. A SIC detection part(160) detects candidate symbol pairs corresponding to each of the candidate symbols of the first stream. A LLR(Log Likelihood Ratio) output part(180) calculates a LLR value by using the candidate symbol pairs.;COPYRIGHT KIPO 2011
