SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

研究了软件无线电中的采样率转换技术，给出两种改进的CIC滤波器结构；(1)基于多相结构和部分尖锐化的CIC抽取滤波器，该结构适用于通带衰落要求不是很高，混迭抑制和滤波速度的要求相对较高的场合(2)一种改进CIC-Rotated Sinc抽取滤波器，该结构在获得好的通阻带特性的前提下，一方面降低了整个CIC滤波器结构的工作速率，另一方面尽可能地降低硬件实现的复杂度。

Alkylphenols are applied widely as the rubber additives surfactants in domestic and industrial products, antioxidants and so on. As it's decomposer, nonylphenol has a steady chemical characteristics and exist widely in environment. As it's molecule structures are similar as 17beta-estradiol in human body, and it can combine with estradiol receptor simulating it, disrupt endocrine system and induce health damage effect. Many studies on environmental endocrine disrupting chemicals approved that NP have weaken estradiol functions.

烷基酚被广泛用作塑料增塑剂、农药乳化剂、纺织行业的整理剂等，作为其降解产物壬基酚(nonylphenol，NP)的化学性质稳定，环境分布广泛，由于其分子结构与人体内雌二醇的分子结构相似，许多环境内分泌干扰的实验研究结果证实壬基酚具有雌激素样作用，可以模拟雌激素与体内雌激素受体结合，干扰机体的内分泌代谢，导致健康危害效应。
