The system is based on a 'subaudible' tone injected after the audio stages into the transmitter during encode and the tone is detected before the audio circuits in the receiver.

这套技术的基本原理如下，进行编码的时候，一个"亚音"音频信号被注入声音信号，并在接收端的音频电路前检测这个音频信号解码。

In theory, the numbers of matched filter and trellis state can be redeced apparently by Laurent Decomposition.So, the complexity of iterative decoding of the SCCPM system can be reduced by using the property of Laurent Decomposition.

将Laurent分解的特性应用于SCCPM系统，理论分析可以有效地减少接收端匹配滤波器以及迭代译码网格状态的数目，明显地降低了SCCPM系统迭代译码的复杂度。

Based on the analytic results, suitable thresholds can be determined according to the system parameters, including the probability of buffer underflow, the probability of buffer overflow and the average playout rate.

该算法改进了Yuang的算法，根据接收端缓冲区的占用情况来动态地调整媒体的播放速率，媒体内同步的要求决定了媒体播放速率的变化范围。

With Walnut Street model as its foundation, observed data were analyzed and processed, the SNR variation models during intermediate and long terms were built, combined with traditional Watterson channel model, the specified HF channel was simulated through SNR prediction.

该算法以Walnut Street信道模型为基础，通过对实际观测数据进行分析处理，建立接收端信噪比变化的中期和长期变化统计模型，联合Watterson模型实现信道模拟。

Using minimum mean square error criterion at receiver, the mean square error matrix submits to inverse wishart distribution at high signal to noise ratio.

当接收端使用最小均方误差准则检测时，检测后的MSE矩阵在高信噪比下服从逆wishart分布。

Theoretical analysis shows that with equispaced null-subcarriers or data subcarriers, the CFO estimation are independent to channel zero locations.

在接收端，以多径区域能量和噪声区域能量之比作为符号定时的判决函数，从而使所形成的峰值更加明显。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
