无线传感器网络的主要功能是实现数据发布,在接收到信息查询时能够以有效的方式传输给查询者.目前的数据发布方式通常基于洪泛机制查询信息,浪费了有限的能源.虽然一些最近的数据发布协议从不同程度上解决了这一问题,但不能保证查询成功率.基于圆形节点分布网络模型提出了一种既能减少能源消耗,又能提高成功率的数据发布模式——直径-弦模式DCS(diameter-chord scheme).该模式利用了每个圆的弦都存在一个直径与之垂直相交的性质.在此基础上提出了Two-Phase协议.它在信息查询时分成两个工作方式不同的阶段进行,在第1段查询不中时触发第2段查找.为了减少Two-Phase的延迟,提出了基于优先级和概率转发两种解决方法.理论分析和实验结果都表明,所提出的数据发布协议具有较好的性能.

The same two-stage decoder as above. However, when transforming the symbols prior to Viterbi decoding, the amplitude information is ignored and only the phase of the received symbol is employed in the metric computation stage.

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.

This sample program generates two sine waves called X and Y. It will then calculate the normalized magnitude and phase of the two waveforms using the following formulas: Mag = sqrt(X^2 + Y^2)/sqrt(GainX^2 + GainY^2) Phase = (long) (atan2PU(X,Y) * 360) The program will prompt the user to change the gain and frequency of the X and Y waveforms.
