基于半实物仿真的FBMC系统性能研究

Study on Performance of Filter Bank Multicarrier System Based on Hardware-in-the-loop Simulation

中文摘要英文摘要

滤波器组多载波(FBMC)系统是第5代移动通信的候选波形之一,相比目前LTE的物理层波形具有很大的优势,本文首先介绍了FBMC系统的调制原理,以及两种FFT变换方式,为了更加接近实际应用场景,利用仪表搭建硬件传输系统,验证不同信道下的误码率性能,如瑞利信道、莱斯信道和频率偏移情况,得出多相网络FFT方案在频偏环境下的表现优于扩展FFT,并且LDPC编码可以使FBMC系统在衰落信道中的性能大幅提升。

Filter Bank Multicarrier (FBMC) is one of the candidates for the next generation wireless communications which has many advantages comparing to the existing physical layer used in LTE. In this paper, a system diagram of FBMC is firstly described and two approaches to implement the FFT transform are introduced. Then for the purpose to be closer to real scenarios, we build a transceiver system to illustrate the bit error rate performance in different channel models like Rayleigh fading, Rician fading and in the condition of carrier frequency offset (CFO). The result indicates that the PPN-FFT scheme outperforms the Extended FFT with the existence of CFO, and transmission coded with LDPC performs excellently in fading channels.
