摘要:
OFDM/OQAM系统由于不需要插入保护间隔,有更高的频谱效率,可以同时抵抗符号间干扰和信道间干扰等特点,已成为传统OFDM系统的一种替代方案.基于新的导频序列结构和OFDM/OQAM的系统特点,分析了系统相邻子载波之间的相关性,提出了一种新的基于导频序列结构的信道估计方法,通过计算相邻子载波的相关系数,有效降低干扰和噪声对信道估计的影响.仿真结果表明,这种导频结构有利于降低噪声对信道估计的影响,从而提高系统的性能.
Abstract:
The OFDM/OQAM system has become an alternative to the traditional OFDM system because it does not need to insert a guard interval, has higher spectral efficiency, and can resist inter-symbol interference and inter-channel interference at the same time. Based on the new pilot sequence structure and Based on the system characteristics of OFDM/OQAM, the correlation between adjacent subcarriers of the system is analyzed, and a new channel estimation method based on the pilot sequence structure is proposed. By calculating the correlation coefficient of adjacent subcarriers, the interference and The influence of noise on channel estimation. The simulation results show that this pilot structure is beneficial to reduce the influence of noise on channel estimation, thereby improving the performance of the system.
