摘要： A Device-to-Device, D2D, communication between a first wireless device (D1) served by a first base station (BS1) and a second wireless device (D2) served by a second base station (BS2), is supported by employing an assisting node (406) which cooperates with the first base station by creating a network code form (f(x1,x2)) of first data (x1) transmitted by the first wireless device and second data (x2) transmitted by the second wireless device. The assisting node then transmits the network coded form of the first and second data to the first base station, such that the first base station is able to determine the second data (x2) based on the received first data (x1) and the network coded form (f(x1,x2)), and to transmit the second data to the first wireless device. Thereby, the first wireless device is able to determine the second data more accurately by combining the second data transmitted by the second wireless device in the D2D communication and the second data x2 transmitted by the first base station.

摘要： A system and method for detecting and selecting peaks in a delay power profile (DPP) signal. An adaptive threshold is used to determine valid paths in the DPP signal. The adaptive threshold is determined by measuring the signal-to-noise ratio of the DPP signal, and setting the threshold to minimize non-detections and false alarms in path estimation. To determine the signal-to-noise ratio, the system uses an iterative process wherein a raw estimate and an improved estimate are made of the noise.

摘要： The present invention provides a search window delay tracking procedure for use in a multipath search processor of a CDMA radio receiver. A channel impulse response is estimated for a received signal containing plural paths, each path having a corresponding path delay. A search window defines a delay profile that contains the plural paths of the received signal. A mean or average delay is calculated for the estimated channel impulse response (CIR), and an error is determined between the mean CIR delay and a desired delay position corresponding to the center of the CIR search window. An adjustment is made to reduce that error so that the center of the search window and the mean CIR delay are aligned. The error may be processed either linearly (in one embodiment) or non-linearly (in another embodiment) to minimize the error and to reduce an influence of noise. A non-linear filtering process includes calculating a delay spread from the mean CIR delay calculated for successive processing cycles of a window delay tracking procedure corresponding to each new input. A difference is determined between the successive delay spreads. Adjustment signal is set equal to the error signal if the difference is less than or equal to a threshold. Alternatively, the adjustment signal is set to zero if the difference is greater than the threshold. Consequently, if the delay spread in the current iteration is significantly different from the delay spread in the previous iteration, the new error sample calculated in the current iteration is considered unreliable, and no adjustment is made.
摘要翻译：本发明提供了用于CDMA无线电接收机的多路径搜索处理器中的搜索窗口延迟跟踪过程。为包含多个路径的接收信号估计信道脉冲响应，每个路径具有对应的路径延迟。搜索窗口定义了包含接收信号的多个路径的延迟分布。计算估计的信道脉冲响应（CIR）的平均或平均延迟，并且在平均CIR延迟和对应于CIR搜索窗口的中心的期望延迟位置之间确定误差。进行调整以减少该错误，使得搜索窗口的中心和平均CIR延迟对齐。可以线性地（在一个实施例中）或非线性地（在另一个实施例中）处理该误差以最小化误差并且减少噪声的影响。非线性滤波处理包括根据对应于每个新输入的窗延迟追踪过程的连续处理循环计算的平均CIR延迟来计算延迟扩展。在连续的延迟差值之间确定差值。如果差值小于或等于阈值，则将调整信号设置为等于误差信号。或者，如果差值大于阈值，则调整信号被设置为零。因此，如果当前迭代中的延迟扩展与先前迭代中的延迟扩展明显不同，则在当前迭代中计算的新的误差样本被认为是不可靠的，并且不进行调整。

摘要： A method and a device are disclosed for despreading incoming signals in a receiver for DS-CDMA systems (DS-CDMA = Direct Sequence Code Division Multiple Access) using Offset-QPSK spreading as the transmitting spreading format combined with arbitrary data modulation formats, such as BPSK and QPSK data modulation formats. The receiver has a PN generator (3; 11) for generating a unique PN sequence signal [s(k)] divided into a real and an imaginary component. The input sampled complex valued numbered signal is divided into inphase and quadrature components. The invention is characterized in that the inphase and the quadrature components (yI and yQ) of the input signal are downsampled to provide either two complex samples per chip period or one complex sample per chip period in which later case the downsampling instants are delayed by a quarter of a chip period. Each downsampled complex signals is correlated with the corresponding segments of the complex PN sequence signal of the receiver. The correlation values obtained for odd and even complex samples of the downsampled input signal are summed, in the case when two samples per chip are provided after downsampling.
