摘要： A source sends an encoded data block during a first time interval to a destination and to a relay. The source sends additional parity bits for the encoded data block during a second time interval. The relay partially decodes that encoded data block to a process-defined end point (typically only a partial decoding), such as a fixed number of decoding iterations. After partial decoding the relay forms a modified data block having corrected information bits and the parity bits of the block it received, and sends the modified data block to the destination, during the second time interval. The destination decodes to a results-defined end point the modified data block it received from the relay using the additional parity bits it received from the source. If that end-point cannot be reached, the destination may begin anew decoding the original encoded data block it received from the source.
摘要翻译：源在第一时间间隔期间将编码数据块发送到目的地和中继。源在第二时间间隔期间为编码数据块发送附加奇偶校验位。继电器将编码数据块部分地解码为过程定义的终点（通常只是部分解码），例如固定数量的解码迭代。在部分解码之后，继电器形成具有校正信息位的修正数据块及其接收的块的奇偶校验位，并在第二时间间隔期间将修改的数据块发送到目的地。目的地使用从源接收到的附加奇偶校验位将从接收器接收到的修改的数据块解码为结果定义的终点。如果无法达到该终点，目的地可能会重新对从源接收到的原始编码数据块进行解码。

摘要： A QRD-M decomposition includes a first and a sequential second stage, at least. In the first stage, M branches are selected from among more than M branches entering the first stage as survive branches from which multiple decompositions are calculated. In the second stage, more than M branches are selected from among those branches entering the second stage as survive branches from which multiple decompositions are calculated. The symbol of the received signal is decided from a branch that is a survive branch of both the first and second stages. The second stage may be within a window that may include additional stages at which the pruning decision down to M survive branches is delayed. One or more windows may be used in a single QRD-M decomposition. In an embodiment, all branches entering the second stage are survive branches. It is shown that the marginal increased computational load increases accuracy.

摘要： The present invention relates to a method, receiving apparatus and computer program product for subblock-wise frequency domain equalization, wherein a data block of a received signal is segmented into at least two subblocks at a receiving end of a transmission channel. The subblocks are then equalized separately in the frequency domain, and equalized subblocks are combined to obtain an equalized signal. Thereby, Doppler induced interference can be suppressed to achieve enhanced robustness to high Doppler and compensate performance degradation due to rapidly varying channels.

摘要： A signal constellation for wireline or wireless multi-carrier communication systems, such as systems using OFDM or MC-CDMA, has points separated from one another by maximizing a distance between conditional probability distributions, such as a Kullbeck-Leibler (KL) distance. Preferably, the constellation points are arranged in concentric circles, with or without a point at the origin, wherein adjacent circles are rotated to maximize an angular distance between points on adjacent circles. Pilot symbols inserted in the transmitted signal are used by a receiver to estimate the channel of the multi-carrier system. Different constellations show optimum performance for different signal to noise ratios, and for different numbers of taps used to estimate the channel, especially in a fast fading environment where there may be fewer pilots per OFDM or MC-CDMA symbol than channel taps.
摘要翻译：用于有线或无线多载波通信系统（例如使用OFDM或MC-CDMA的系统）的信号星座通过使条件概率分布（例如Kullbeck-Leibler（KL））距离之间的距离最大化而具有彼此分离的点。优选地，星座点以同心圆布置，具有或不具有原点的点，其中相邻的圆圈被旋转以最大化相邻圆上的点之间的角距离。在发送信号中插入的导频符号被接收机用于估计多载波系统的信道。不同的星座显示不同信噪比的最佳性能，以及用于估计信道的不同数量的抽头，特别是在快速衰落环境中，每个OFDM或MC-CDMA符号的导频可能比信道抽头少。

摘要： A CDMA receiver includes a receiver input for coupling to signal outputs of Nrx receive antennas, a matched filter and a whitening filter system for coupling the receiver input to an input of the matched filter. The whitening filter system contains NsNrx parallel filters receiving during each symbol internval NsNrx new signal samples via a signal connection matrix such that a first parallel filter receives only one of the new samples, a second parallel filter receives the same sample as the first, and one additional sample, and such that an nth parallel filter receives the same n-1 samples as the first n-1 filters, plus one of the remaining samples. The whitening filter system has Nrx outputs for outputting filtered signal samples such that a filtered signal sample appearing in the Nrx outputs does not correlate with any other filtered signal sample appearing in Nrx outputs.
