Signal Separation for Automatic Dependent Surveillance-Broadcast Using Improved Single Antenna Project Algorithm
-
摘要: 广播式自动相关监视(ADS-B)作为一种新的监视技术正受到国际民用航空组织(ICAO)的大力推广。然而，由于ADS-B信号传输具有随机性，多条信号交织问题不可避免。该文提出一种改进的单天线投影算法(PASA)。利用单通道分离交织信号，首先对单通道接收到的数据提出一种新的矩阵重构方式，从而降低两条信号之间的相对时延和频偏要求；然后利用投影算法分离交织信号。仿真实验结果验证了该算法的有效性。Abstract: The Automatic Dependent Surveillance-Broadcast (ADS-B), as a new surveillance technology, is being vigorously promoted by International Civil Aviation Organization (ICAO). However, overlapping among multiple signals is inevitable because of the randomness of ADS-B signal transmission. An improved Project Algorithm Single Antenna (PASA) algorithm which separates the overlapping signals with one single channel is proposed. Firstly, a new matrix reconstruction method for the data that received by single channel is proposed to decrease the requirement of relative time delay and frequency difference between two ADS-B signals, and then the overlapping signals can be separated by utilizing the projection algorithm. The effectiveness of the algorithm is verified by simulation experiments.
