摘要 提出了一种基于导频辅助的宽带干扰(WBJ)差分检测算法,不但能判断干扰出现的位置,而且还能计算出每个子载波的SINR(包括干扰和噪声的信噪比)。通过理论的分析和仿真,验证了本文提出的算法能够比较准确地检测出宽带干扰的位置和每个子载波的信干噪比(SINR)。 In this paper, a differential algorithm is presented based on pilot-aided for Orthogonal Frequency Division Multiplexing (OFDM) systems under Wide Band Jamming (WBJ). The position of jammed pilot subcarriers can be detected, and the SINR(the ratio of signal power and noise including jamming and noise) of jammed pilot subearriers can be calculated. By analyzing on simulation system, it is verified that the proposed algorithm can accurately detect the position of wide-band jamming and calculate SINR of each subcarriers.
