自适应干扰抵消系统的性能分析与设计

Performance analysis and design of adaptive interference cancellation system

论文对自适应干扰抵消系统的性能及影响系统性能的各种因素做了详细的分析,并导出了定量表示式。在此基础上,提出了一种改进型系统。在不增加设备复杂度的前提下,使系统性能改进14～30dB。最后给出了一个设计示倒及实验结果。

The paper analyses in detail the system performance as well as all factors which affect the system performance. Also, a quantitative expression for the effect of all these factors on the performance of the system, on the basis of which an improved system is presented. The performance of the system has been improved by 14～30dB on condition-that the complexi- ty of the systcm remains unchanged. Finally, a design example and experimental results are given.
