本文描述一种新的信号处理技术,用来在直接序列扩频通信接收系统中抑制干扰,基本思路是最佳化检测处理,动态地对抗通用的干扰.这用估算干扰统计,然后使用这个信息导出非线性转换加到“信号—加—噪声”上的方法来完成,和干扰变化统计一样,实测的分布和合成转换也这样做.这个配合是“开环”的,因此不会出现收敛问题.对于比作者所知道的用以前任何实现技术可以处理的宽带干扰调制,都能够得到较大的改进(几十dB).
This article describes a new signal processing technique used to suppress interference in direct-sequence spread-spectrum communication reception systems. The basic idea is to optimize the detection process and dynamically counter common interference. This estimates interference statistics and then uses this information Exporting the non-linear transformation to “Signal-plus-Noise ” is done in the same way as interfering with change statistics, and the actual distribution and synthesis transformation does the same. “This cooperation is ” open loop "and therefore not There will be a convergence problem that can be greatly improved (tens of dB) for the wideband interference modulation that the authors know can be handled with any of the previous implementations.
