摘要

提出了联合处理脉冲和 OFDM（N-OFDM）信号的方法。获得了在脉冲辐射源存在的情况下，OFDM（N-OFDM）信号振幅等级分散的下克拉默-拉奥边界的相应分析关系。通过数学建模，确定了集成雷达和电信系统中脉冲信号背景下 OFDM（N-OFDM）信号解调方法的特性和局限性。经确定，脉冲信号源和 OFDM 信号源之间的角度距离不小于数字天线阵列图案次波束宽度的 0.75，不会影响 OFDM 信号幅度的准确性。这同样适用于有源干扰。

Spatial Selection-Based Intelligent N-OFDM Signal Processing in Wireless Communication Systems

The method of joint processing of pulses and OFDM (N-OFDM) signals is proposed. The corresponding analytical relations for the lower Cramer-Rao boundary on the dispersion of OFDM (N-OFDM) signals amplitude ratings in the presence of sources of pulsed radiation are obtained. Using mathematical modeling properties and limitations of the demodulation method of OFDM (N-OFDM) signals in the background of impulse signals in the integrated radar and telecommunication systems are established. It is determined that the use of the angular distance between the pulsed and OFDM signals sources at a value that is not less than 0.75 widths of the secondary beam of the digital antenna array pattern does not affect the accuracy of the OFDM signal amplitudes. The same applies to the active interferences.

期刊介绍： The International Journal of Computing Journal was established in 2002 on the base of Branch Research Laboratory for Automated Systems and Networks, since 2005 it’s renamed as Research Institute of Intelligent Computer Systems. A goal of the Journal is to publish papers with the novel results in Computing Science and Computer Engineering and Information Technologies and Software Engineering and Information Systems within the Journal topics. The official language of the Journal is English; also papers abstracts in both Ukrainian and Russian languages are published there. The issues of the Journal are published quarterly. The Editorial Board consists of about 30 recognized worldwide scientists.
