浅谈权利要求中的非技术特征

非技术特征是涉及专利法排除主题的非发明的特征。通过两个法院判决发现,目前对于包含有非技术特征的权利要求是不是技术方案的判断,虽然都采用了技术手段、技术问题和技术效果的三要素判断方法,但仍然无法得到一个确切的结论,本文通过研究欧美的审查实践提出了含有非技术特征的权利要求的判断与审查方法。

Code-aided Interference Suppression in Direct Sequence Spread Spectrum Systems with Eigenvector Sign Spreading Code

For direct sequence spread spectrum (DSSS) communication systems suffering interference, it is known that code-aided interference suppression technique outperforms all of the previous linear or nonlinear methods. In this paper, we proposed an improved code-aided technique which can improve the system performance greatly by using the eigenvector sign (EVS) spreading sequence which depends on the statistical characteristics of the interference and the thermal noise.
