APPARATUS AND METHOD FOR PREDICTING ESTIMATING SINR IN SPATIALLY MULTIPLEXED MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM

摘要

PURPOSE: A device and method for predicting a signal-to-interference and noise ratio in a space multiple antenna system are provided to simply predict a performance of a detector which show a performance of a ML detection technique in a space multiple antenna system. CONSTITUTION: A channel is presumed by using a plurality of stream which is received through a plurality of receiving antenna(S310). Capacity of a SM MIMO system is decomposed into a capacity of a plurality of virtual SIMO(Single Input Multiple Output) system by using the presumed channel(S320). Loss generated by a plurality of stream receives through a plurality of receiving antenna is calculated(S330). A SINR of each stream is predicted by using loss and capacity of a plurality of virtual SIMO system(S360).
