摘要： A general framework for parametric filters is based on belief condensation (BC), which can cope with highly nonlinear and non-Gaussian system models. The methodology exploits the specific structure of the problem and decomposes it in such a way that the linear and Gaussian part can be solved in closed form, while the remaining parts are addressed by an optimization process, referred to as BC. Simulation results show that the performance of the proposed BC filter is close to that of the particle filter, but with a much lower complexity.

摘要： A method and corresponding apparatus for searching for a signal is presented. The apparatus may be configured to select a first bin within a range of bins characterizing an uncertainty region. The bins may represent a phase within a bandwidth of interest. The apparatus may also be configured to compare a local signal, having a phase corresponding to the first bin, with a received signal, the received signal being received via a transmission medium. The apparatus may report whether the local signal matches the received signal. The apparatus may assign weightings to the bins if the local signal does not match the received signal. If a match is not found, the apparatus may select a next bin according to the weightings or according to characteristic of the transmission medium until a matching bin is obtained. One benefit of the search is reduced search time to allow, for example, a cell phone to synchronize the phase of a received signal more quickly than is currently done.
摘要翻译：提出了一种用于搜索信号的方法和相应的装置。该装置可以被配置为在表征不确定性区域的箱的范围内选择第一仓。箱可以表示感兴趣的带宽内的相位。该装置还可以被配置为将具有对应于第一仓的相位的本地信号与接收信号进行比较，所接收的信号经由传输介质被接收。该装置可以报告本地信号是否匹配接收的信号。如果本地信号与接收到的信号不匹配，则该设备可以向箱分配权重。如果没有找到匹配，则设备可以根据加权或根据传输介质的特性来选择下一个bin，直到获得匹配的bin。搜索的一个好处是减少了搜索时间，以允许例如手机比接收到的信号的相位更快地同步。

摘要： A system and corresponding method using a cooperative localization technique for self identifying a location of a wireless device in a wireless network is presented. The system may estimate an arbitrary signal metric as a function of a signal received by the wireless device from the at least one other wireless device in the wireless network. The system may also convert at least one belief representing a distribution of at least one possible location of the at least one other wireless device to generate at least one converted belief. The system may further determine a self-belief as a function of the at least one converted belief and identify a self location, as a function of the self-belief, within the wireless network.

摘要： A wireless communication system experience interference from other wireless communication networks. A method for designing wireless communication systems subject to interference is proposed based on a realistic interference model which accounts for the propagation effects introduced by the wireless environment (such as path loss, shadowing, and multipath fading), and for the spatial scattering of transmitters (using a Poisson field). The method accounts for tradeoffs between network parameters, such as signal-to-noise ratio (SNR), interference-to-noise ratio (INR), path loss exponent, spatial density of the interferers, and error probability. Advantages of this method include: 1) a unified framework for designing a wireless system, subject to cumulative interference and noise, incorporating a wide range of performance metrics; and 2) a general application that covers a broad class of wireless communication systems and channel fading distributions.
摘要翻译：无线通信系统经受来自其他无线通信网络的干扰。提出了一种用于设计受干扰的无线通信系统的方法，该实际干扰模型考虑了由无线环境引入的传播效应（如路径损耗，阴影和多径衰落）以及发射机的空间散射（使用泊松场）。该方法考虑了网络参数之间的折衷，如信噪比（SNR），干扰信噪比（INR），路径损耗指数，干扰源的空间密度和误差概率。该方法的优点包括：1）设计无线系统的统一框架，受到累积干扰和噪声的影响，并结合广泛的性能指标; 和2）涵盖广泛类别的无线通信系统和信道衰落分布的通用应用。

摘要： A wireless communication system and a detect-and-multiplex (DAM) spectrum sharing technique eliminate contention by secondary spectrum users by multiplexing multiple access methods. Suitable multiple access methods include time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), space division multiple access (SDMA), orthogonal frequency division multiple access (OFDMA), spectral nulling (SN) or a hybrid scheme (HS) based on a combination of two or more of the above techniques. Unlike, detect-and-avoid (DAA) multiple access methods, the DAM method increases spectrum usage efficiency, and allows more users to share the same region of the spectrum.
