In order to eliminate intercarrier interference of orthogonal frequency-division multiplexing communication systems, based on interference coefficients analysis and reasonable estimation, a novel decorrelation interference cancellation scheme using frequency-domain equalization was proposed.

为消除正交频分复用系统中的载波间干扰，在对干扰系数分析与合理估计的基础上，提出了一种基于频域均衡思想的解相关干扰抑制方案。

To handle co-antenna interference, intersymbol interference and intercarrier interference caused by insufficient cyclic prefix, a MMSE-based Turbo per-tone equalization is presented for MIMO OFDM systems in this paper.

摘要在MIMO OFDM系统中，为了对抗同天线干扰及由于保护间隔不足而引起的码间干扰和载波间干扰，该文给出了一种基于MMSE的Turbo子载波均衡器。

Wavelet packet based multicarrier modulation is a technique combining wavelet analysis theory and multicarrier modulation perfectly. It provides high frequency efficiency, better performance against intersymbol interference, intercarrier interference, tone and impulse interference and can transmit multirate symbols easily.

小波包多载波调制技术是一种新兴的多载波调制技术，是小波分析理论和多载波通信的完美结合，具有频谱利用率高和良好的抗符号间串扰、信道间干扰、脉冲干扰和单频干扰的优良特性，并且易于多速率传输。

Inherent inter-symbol and inter-carrier interference elimination ability of orthogonal frequency division multiplexing system attribute to its cyclic prefix. But the case of multipath fading channels whose the channel impulse response length exceeds the duration of cyclic prefix causes intersymbol interference and intercarrier interference, which may degrade system performance severely.

正交频分复用系统中的循环前缀具有一定的抗码间干扰和子载波间干扰的能力，但是当多径衰落信道的最大信道脉冲响应长度超过了循环前缀长度时，OFDM系统的性能将会严重下降。

When vitamin C concentration was ≤0.5g/L, both vanadic acid oxidation assay and diazo method bad no interference. When triglyceride was ≤6 mmol/L, the vanadic acid oxidation assay had no interference and the diazo method had significant interference.

维生素C≤0.5 g/L时对钒酸氧化法和重氮法均无干扰，三酰甘油≤6 mmol/L时对钒酸氧化法无干扰，对重氮法有明显干扰。

With regard to the government interference question, economics often takes it as an economic variable quantity. As in economics, adopting different premising hypothesis will lead to different conclusions, which means that economics only explains various possible choices of government interference. Choice of certain government interference mode only reflects the economist's value tendency to a great extent.

对于政府干预问题，经济学往往把其作为一个经济变量来看待，由于在经济学中，采用不同的前提性假设会导致不同的结论，这意味着，经济学只是对政府干预的诸多可能的选择进行解释，某种政府干预模式的选择很大程度上仅仅反映经济学家本人的价值观倾向。

By means of the different interference phase formed by light beams with different wavelengths in the same light path difference and the superposing of interference signals of different spectral components, ultimate interference signal is formed.

振动系统产生干涉光路的光程差，形成干涉信号的调制相位差，通过不同光波长在相同光程差条件下形成的不同干涉相位，通过对不同光谱分量的干涉信号叠加，形成最终的干涉信号。

A kind of interference, called direct access interference, is found in the calculus of Mobile Resources, which will cause more damage than the grave interference one finds in the calculus of Mobile Ambients,because in MR malicious environments or contexts can freely access the sensitive resources inside a process.

在移动资源演算中发现了一种干扰现象，称为直接访问干扰，该现象比移动灰箱演算中的墙干扰现象更具破坏力，因为在MR中恶意的环境或上下文可以不受限制地访问进程内部的敏感资源。

As a result, the research based on sample data shows that the velocity distribution of vehicles has different characteristics under different interference state, and vehicles driving velocities are significantly different under the friction interference and block interference.

基于样本的研究结果表明，自行车对小汽车和大客车的影响程度有显著的差别，同时机动车在摩擦干扰和阻滞干扰两种状态下的行驶速度特征有明显的不同。

Interference Fit Fit with interference (Including minimum interference zero).

过盈配合具有过盈的配合。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
