| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes iterative hard dicision decoding in a linear multilevel QAM reciever for overloaded MIMO. A serilal interference canceller(SIC) combined with the lattice reducution for overloaded MIMO is applied as a linear dedector. It can enhance downlink user throughput in spite of the number of antennas on a terminal. In addition, this paper proposes new signal demapping tecniques that converts the output signals from SIC. The proposed decording evaluated by computer simulations in a 6×2 overloaded MIMO sysytem with multilevel modulations, such as 64QAM. As a result, the proposed decoding gain 1[dB] at the BER of 10^-4 when 40 iteration is applied. Moreover, we consider correlation of bit error about the proposed demapping. | |
