摘要

针对MIMO编码FBMC系统，提出了一种基于叠加导频的信道估计技术。在编码FBMC中，利用符号随时间的扩散来减轻固有干扰。基于叠加导频的信道估计是一种通过在一组选定的子载波上传输导频符号和数据符号来提高频谱效率的技术。该系统实现了与MIMO-OFDM相同的误码性能和均方误差性能，并提高了频谱效率。从两个方面提高了光谱效率。通过消除循环前缀开销和避免使用专用子载波为飞行员。

Superimposed Pilot Based Channel Estimation for MIMO Coded FBMC Systems

In this paper superimposed pilot based channel estimation technique is proposed for MIMO coded FBMC systems. In coded FBMC intrinsic interference is mitigated by using spreading of symbols across time. Superimposed pilot based channel estimation is a technique that improves the spectral efficiency by transmitting the pilot symbols along with the data symbols on a set of selected subcarriers. The proposed system achieves the same bit-error performance and mean square error performance as that of MIMO-OFDM with an additional advantage of improved spectral efficiency. The spectral efficiency is improved in two ways. By removing the cyclic prefix overhead and by avoiding the use of dedicated subcarriers for pilots.
