Abstract: <P>PROBLEM TO BE SOLVED: To provide a MIMO receiving apparatus which prevents a delay time from being prolonged by deinterleave and re-interleave processes, even when the number of loops of iterative processing for interference cancellation is increased.  <P>SOLUTION: In a receiving apparatus 201, the iterative processing of an IDD loop for interference cancellation is performed by interference replica cancelers 56-1 to 56-4, multipliers 58-1 to 58-4, adders 59-1 to 59-2, log likelihood ratio calculators 60-1, 60-2, LDPC decoders 61-1, 61-2, switchers 63-1, 63-2 and interference replica generators 62-1, 62-2. Furthermore, processing with deinterleavers 55-1 to 55-3 is performed outside the IDD loop for interference cancellation. Thus, even when the number of times of the repetition of the IDD loop is increased, the number of times of deinterleaving and re-interleaving processes is not increased therewith, thereby preventing a delay time from being prolonged.  <P>COPYRIGHT: (C)2010,JPO&INPIT
