[0116] figure 1 is a diagram showing the configuration of the wireless communication device 100 in the first embodiment of the present invention. exist figure 1 Only the receiving configuration is displayed in the wireless communication device 100 of the figure 2 The transmission configuration is displayed in the wireless communication device 100a of . The reception configuration in the embodiment is a configuration in which iterative decoding is performed using a Parallel Interference Canceller (PIC). The following will follow figure 1 with 2 The operation is discussed in the order:
[0117] First, refer to figure 2 The transmission operation of the wireless communication device 100a is discussed. The wireless communication device 100a performs spatial multiplexing transmission of M transmission sequences from a plurality (M, M>1) of antennas 26-1 to 26-M (hereinafter will be referred to as spatial multiplexing streams) . figure 2 The configuration of the wireless...

[0257] Figure 4 is a diagram showing the configuration of the wireless communication device 100b in the third embodiment of the present invention. exist Figure 4 In the wireless communication device 100b of , only the receiving configuration is shown, and the transmitting configuration is the same as figure 2 This configuration of the wireless communication device 100a shown in is the same, and therefore the transmission operation will not be discussed again.
[0258] As a reception configuration in this embodiment, it shows a configuration in which iterative decoding is performed using a parallel interference canceller (PIC). The third embodiment differs from the first embodiment in that a wireless communication device has an error component estimator 15 for estimating an error component based on an input signal, which is different from the error component estimator 13 in the first embodiment. That is, error component estimator 15 estimates error components based on the...
