摘　　要：信号同步是无线通信中最为关键的一步。同步质量的好坏,决定了通信能否建立。针对存在较强有色干扰的通信环境,提出了基于空域滤波的采用雅可比旋转法实现奇异值分解的信号抗干扰同步算法。具有较强的抗干扰性能,减少了计算量,有利于工程实现。在实际环境中对算法进行了验证。Signal synchronization is the most critical step in wireless communication. The quality of synchronization determines whether the communication can be established. For the communication environment with strong colored interference, a signal anti-interference synchronization algorithm based on spatial filtering is proposed. This algorithm uses the Jacobi rotation method to realize singular value decomposition. It can reduce the amount of calculation and has strong anti-interference performance. Experiments are conducted in practical scenarios and the results demonstrate that this algorithm can benefit the engineering implementation.
