Abstract

Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which uses the subcarrier indices as a source of information, has attracted considerable interest recently. Motivated by the index modulation (IM) concept, we build a circular convolution filter bank multicarrier with index modulation (C-FBMC-IM) system in this paper. The advantages of the C-FBMC-IM system are investigated by comparing the interference power with the conventional C-FBMC system. As some subcarriers carry nothing but zeros, the minimum mean square error (MMSE) equalization bias power will be smaller comparing to the conventional C-FBMC system. As a result, our C-FBMC-IM system outperforms the conventional C-FBMC system. The simulation results demonstrate that both BER and spectral efficiency improvement can be achieved when we apply IM into the C-FBMC system.

指数调制的圆卷积滤波器组多载波系统
利用子载波指数作为信息来源的正交频分复用技术(OFDM-IM)近年来引起了人们的广泛关注。在索引调制(index modulation, IM)概念的启发下,本文构建了一个带索引调制的圆卷积滤波器组多载波(C-FBMC-IM)系统。通过与传统的C-FBMC系统的干扰功率比较,研究了C-FBMC- im系统的优点。由于一些子载波只携带零,最小均方误差(MMSE)均衡偏置功率将比传统的C-FBMC系统更小。因此,我们的C-FBMC- im系统优于传统的C-FBMC系统。仿真结果表明,在C-FBMC系统中应用IM可以同时提高误码率和频谱效率。
