干扰消除是DSSS系统中的重要技术,文中介绍了直扩系统中一种基于DWT的干扰消除技术,并对该技术进行了计算机仿真。仿真结果表明,这种基于小波变换的干扰消除技术对DSSS系统的性能有较大的改善。
Interference elimination is an important technology in DSSS system. In this paper, a DWT-based interference cancellation technique in DSSS is introduced and the computer simulation of this technique is carried out. Simulation results show that this wavelet transform-based interference cancellation technology has greatly improved the performance of DSSS system.
