摘要： A method of detecting transient changes in the distribution of a discrete time series includes: operating in a sparse mode wherein, at sniff periods successively repeated at a first rate, at most K test phases are performed, K being an integer superior or equal to two, each test phase consisting of analyzing, by a sampling stopping time determination unit, samples of the time series captured by a sampler at sampling times according to a second rate which is higher than the first rate to provide a positive or negative result of the test phase. If the results of K successive test phases of a sniff period are each positive, the method switches to operate in a dense mode wherein the sampler is operated to continuously capture samples of the time series at sampling times according to the second sampling rate.
摘要翻译：本发明涉及一种检测离散时间序列的分布的瞬时变化的方法，包括以下步骤： - 以稀疏模式操作，其中在以第一速率连续重复的呼吸周期中，至多执行K个测试阶段， K是大于或等于2的整数，每个测试阶段包括通过采样停止时间确定单元根据高于第一采样率的第二采样率在采样时间采样采样器采集的时间序列采样到提供测试阶段的正面或负面结果; - 如果嗅探周期的K个连续测试阶段的结果均为正，则切换到以密集模式操作，其中采样器被操作以根据第二采样率在采样时间连续捕获时间序列的采样; 其中一旦在所述嗅探期的测试阶段中对所述俘获的样本的分析是否定的，则嗅探期结束，停止对所述时间序列的采样直到下一嗅探期; 并且其中只有当所述嗅探周期的前一个测试阶段的结果是肯定时才执行嗅探周期的下一个测试阶段，所述下一个测试阶段是通过捕获和分析与前一个测试阶段至少一样多的样本来执行的。

摘要： A wireless communication device is provided to carry out correlation peak detection processing properly and efficiently in intermittent receiving unit. If a correlation peak is not detected in a first period in which a correlation peak detecting unit (22) detects the correlation peak at a default frequency and a first frequency in a detecting period of a coarse frequency deviation detecting unit (23) in the first period, a control unit (25) makes the correlation peak detecting unit (22) carry out the peak detection at the first frequency in a second period. If the correlation peak is detected in the correlation peak detecting unit (22) and a second frequency is detected in a detecting period of a fine frequency deviation detecting unit (24) in the first period, the control unit (25) makes the correlation peak detecting unit (22) carry out the peak detection at the first and second frequencies in a third period.

摘要： A DSSS detector (19) for detecting a synchronization between an aperiodic spread spectrum signal (r(nT
c )) having a plurality of chips (r(n) ) and a spreading sequence (PN) having a plurality of chips (pi). The DSSS detector (19) has at least one branch (16) adapted to receive the spread spectrum signal, and the branch is formed by a plurality of correlators (1) cascade connected to each other and separated one another by a branch delay block (20). Each correlator (1) has a multiplier (12) for correlating chips (pi) of the spreading sequence (PN) with chips (r(n) ) of the spread spectrum signal (r(nT
c )) and generating each an own correlation value (y(n)). The DSSS detector (19) further has a matching detector (22, 23, 27) receiving the correlation values (y(n) ) and detecting when all the correlation values (y(n)) are maximum.
