PROBLEM TO BE SOLVED: To solve a problem of a wireless communication device with repetitive-decode receiving of a spatial multiplexed signal that a deterioration of a reception characteristics results from interference signal components when a symbol in which discrimination is erroneous is included at a time of an interference cancellation, and when error causes result from a propagation channel estimation deviation, a hard deviation (carrier frequency deviation, sampling frequency deviation) are included. SOLUTION: The wireless communication device 100 is provided with an error estimation unit 13 which estimates a deviation of a replica signal at a time of interference cancellation and a weighting unit 14 which weights likelihood information on a spatial multiplexed signal separated and compounded after interference cancellation based on the output of the error estimation unit 13. Accordingly, an excellent reception characteristic is obtained even when the deviation of the replica signal is included at the time of interference cancellation. COPYRIGHT: (C)2008,JPO&INPIT |
