| Abstract(in English) | This report proposes Twin Turbo MIMO-OFDM. The advanced iterative decoder, which is called Twin Turbo Decoder (T2), improves the transmission error rate of conventional turbo decoders using the correlation information among the bits mapped on an identical symbol of multi-level modulation and updating the bit likelihood. When T2 is applied to MIMO-OFDM, the required E_S/N_0 can be reduced more effectively than when T2 is applied to SISO or SIMO because T2 can use the correlation among the bits not only mapped on an identical symbol but also transmitted from different antennas. Computer simulations verify that the required E_S/N_0 of T2 MIMO-OFDM using 16QAM is 1.5dB lower than that of a normal turbo decoder. |
