摘要：
The combination of dual-polarized MIMO and ultra-multilevel OFDM is considered in the next-generation digital terrestrial broadcasting. Also, the use of Non-Uniform QAM(NU-QAM) as a new sub-carrier modulation scheme has been proposed. In the mobile reception of OFDM signal, inter-carrier interference(ICI) is generated by Doppler-spread. MIMO-ICI canceller using iterative detection can improve the reception characteristics with complexity reduction. In this paper, the reception characteristics are evaluated for dual-polarized MIMO ultra-multilevel OFDM using NU-QAM under mobile reception.
