| 摘 要： | 在双扩散信道环境下,已证明LOFDM系统误码性能优于正交频分复用(OFDM)系统。文章结合T urbo均衡技术和LOFDM系统提出了一种双扩散信道条件下拥有良好性能的T-LOFDM系统,并阐述了其工作原理。仿真实验表明:在双扩散信道条件下,T-LOFDM系统具有非常良好的性能,其误码率性能明显优于LOFDM结合MM SE均衡的系统,也明显优于OFDM结合T urbo均衡的系统。

| Abstract: | In doubly-dispersive channels condition,we have proved the bit error performance of LOFDM system much better than OFDM system.By combing Turbo equalization and the system of LOFDM,the paper proposes one T-LOFDM system 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 system is much better than the system of LOFDM system combined with MMSE equalization,also much better than th... |
