摘要 Turbo均衡能够通过迭代的方式对接收信号进行多次均衡与信道解码处理,从而提高接收机性能。在SUI信道下,对采用单载波调制体制进行信息传输的Turbo均衡性能进行了仿真研究。系统通过对引导符号序列在频域进行基于MMSE准则的信道估计,获取SUI信道的信息,在时域进行基于线性MMSE准则的Turbo均衡处理。Matlab仿真结果表明,相对于传统的单载波频域均衡方案,Turbo均衡的方案显著提高了整个传输系统的抗衰落性能。 Turbo equalization is an iterative process that repeats equalization and channel decoding to improve receiver performance. The performance of Turbo equalization over SUI channels when using single carrier modulation to transmit information is simulated and researched. The information of SUI channel is obtained through MMSE criterion based channel estimation in frequency domain over pilot symbol sequence,and linear MMSE based Turbo equalization in time domain is carried out. The results of Matlab simulation indicate that Turbo equalization can apparently improve the anti-fading performance of the transmission system compared with the traditional solution of SC-FDE.
