存在定时偏移的UFMC系统信号与干扰分析

doi:10.3969/j.issn.0255-8297.2022.05.008

Abstract

Abstract: As the actual arrival time of a signal arriving universal a filtered multi-carrier (UFMC) receiver is inconsistent with the expected arrival time, timing offset (TO) occurs, which introduces inter symbol interference (ISI), destroys the orthogonality of subcarriers, and decreases the communication quality. In order to analyze the influence of TO on UFMC systems, this paper analyzes the signal and interference of UFMC systems with TO, derives corresponding theoretical expressions, numerically calculates and compares the signal to interference ratio (SIR) under different waveform filter lengths and different TOs, and simulates and compares the symbol error rate (SER) of UFMC systems in different situations. Simulation results show that the value of TO is positively correlated with the signal interference intensity, and the filter length is inversely correlated with the SER of systems.

Key words: universal filtered multi-carrier (UFMC) system, timing offset, signal to interference ratio (SIR), signal interference analysis
