Summary:Disclosed is a method for deciding a signal detection order in a mobile communication system that supports an adaptive modulation technology. The detection order that maximizes a channel, in which a product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, maximum is selected by obtaining the effective SINR and performing a bit allocation with respect to the detection orders of each detection order, and thus an average error probability can be minimized. In the case in which the number of antennas is increased, the detection orders of all the possible cases are not considered, but the detection order that maximizes the channel, in which the product of the minimum symbol distance for each modulation rate and the effective SINR becomes minimum, is selected with respect to a forward ordering and a reverse ordering.
