Abstract
A receiver for ICI cancellation in a MIMO system is provided, in which a detection orderer determines a subcarrier detection order according to SINRs of subcarriers in an I-CMOS, a detector receives a vector on the subcarriers and a priori information from a decoder according to the subcarrier detection order and iteratively estimates the received vector using the a priori information, and the decoder decodes an ICI-cancelled signal according to the estimate.
