Lattice-OFDM Receiver based on a Turbo Equalization

In doubly-dispersive channels condition, we have proved the bit error performance of LOFDM system much better than OFDM system. The paper combines Turbo Equalization proposes one LOFDM Receiver structure (T_LOFDM) on the condition of doubly-dispersive channels, and expatiates its work theory. Simulation results validate: In doubly-dispersive channels condition, the bit error performance of T_LOFDM Receiver much better than the receiver of LOFDM system use MMSE equalization, also much better than the receiver of OFDM system use Turbo equalization.
