散射通信中OFDM/OQAM的ICI和ISI分析
Analysis of ICI and ISI in Troposcatter Communication Based on OFDM/OQAM Modulation
摘要
Abstract
Troposcatter communication plays an important role in wireless communication for its specific function. But it has the problem of big loss in transmission and multipath communication and fading. Offset-QAM based OFDM,without Cyclic Prefix,takes OFDM’s advantage of anti-multipath interference. It can eliminate inter-carrier interference and inter-symbol interference in multipath channels by filter-bank instead of guard interval to improve the utilization rate of frequency spectrum. The paper builds the tapped delay line model of the troposcatter channel and analyzes the mathematic statistic character of ISI and ICI. It makes a comparison between OFDM/OQAM and CP-OFDM/QAM. The simulation results demonstrate the advantage of OFDM/OQAM over traditional OFDM in the suppression of ICI and ISI in troposcatter channel. There is an obvious reduction of Bit Error Rate. The paper provides direction for the realization of high speed and large capacity and high reliability scattering communication.关键词
