  • To handle co-antenna interference, intersymbol interference (ISI) and intercarrier interference (ICI) caused by insufficient cyclic prefix, a MMSE-based Turbo per-tone equalization is presented for MIMO OFDM systems in this paper. A Soft-Input Soft-Out (SISO) per-tone equalizer exchanges soft information with SISO channel decoder through iterative process. Simulation results show that the proposed Turbo per-tone equalizers can effectively exploit time diversity and space diversity and offer performance gain over non-iterative equalizers.
