METHOD FOR DECIDING REDUCED CANDIDATE SET IN MIMO SYSTEM

摘要

PURPOSE: A method for deciding a candidate symbol group in a multi-antenna system is provided to adjust the size of a candidate symbol group according to a channel condition, thereby reducing complexity of a tree search algorithm. CONSTITUTION: Candidate symbol group information is saved(1901). The candidate symbol group information corresponds to a condition number value of a channel. A condition number of the current channel is calculated(1902). The calculated condition number value and the saved condition number value are compared. According to the comparison result, a candidate symbol group of the current channel is determined(1903).
