Satellite communication has the characteristics of wide coverage and large communication
capacity, and is not easily affected by land disasters. It is quite suitable as a supplement to …

In a non-cooperative context, the receiver has no information about communication
parameters; therefore, it must perform communication forensics, which is the process of …

针对传统单通道异步直接序列码分多址(DS-CDMA) 信号信息序列及伪码序列(PN)
难以估计的问题, 该文提出一种基于平行因子(PARAFAC) 的多通道盲估计方法 …

In this paper, we propose a novel algorithm for blind estimation of a linear scrambler, which
is a synchronous scrambler or a self-synchronous scrambler, in direct sequence spread …

In a non-cooperative context, a receiver has to estimate the communication parameters
without any prior knowledge of the transmitter, which is highly demanding. Estimating a self …

由于长短码直扩码分多址(LSC-DS-CDMA) 信号包含了多个用户的长码和短码,
已有的直扩码分多址信号的盲伪码估计方法不再适用. 为此该文提出一种基于矩阵填充和三阶 …

针对软扩频信号因采用了编码技术使得伪码序列难以估计的问题, 该文提出一种基于K-means
聚类改进的软扩频信号伪码序列盲估计方法. 该方法首先以单倍伪码周期的窗长对接收信号进行 …

Self-synchronous scramblers are more difficult to blindly estimate than synchronous
scramblers because their input sequence affects the state of the scrambler's linear feedback …

A novel acquisition scheme of pseudo-noise (PN) codes is proposed for spreading satellite
communication systems relying on the proposed multi-voter model of this paper. Based on …

Aiming to solve the problem of the distinction of scrambled linear block codes, a method for
identifying the scrambling types of linear block codes by combining correlation features and …
