    • The present invention relates to orthogonal frequency-division multiplexing (OFDM) communication systems with multiple transmit antennas receive antennas, and in particular to methods for inserting scattered pilots (SPs) into the transmit signals of such OFDM systems, for estimating channel properties on the basis of the scattered pilots, a multi-antenna OFDM transmitter, and an OFDM receiver. In this context, it is the particular approach of the present invention to keep the same SP pattern like in the single-transmitter case, to partition the pilots into as many subsets as there are transmitters (transmit antennas), and to interleave these subsets both in time and in frequency. In this manner, the granularity of pilots of the same subset is reduced. This offers increased flexibility in designing the scattered pilot patterns and greater accuracy of the estimated channel properties.

    • The present invention relates to digital data communication and provides an efficient method for generating multi-dimensional constellations for digital data modulation with a high degree of modulation diversity, a method for transmitting and receiving data on the basis of such constellations, and a corresponding apparatus. This is achieved by considering only multi-dimensional rotation matrices with all elements on the diagonal having the same first absolute value and all other elements having the same non-zero second absolute value. In this manner, multi-dimensional rotation matrices can be generated having only a single independent parameter and a structure that is as regular as possible. The independent parameter can be configured in order to minimize the error probability for various constellation sizes.
    • 本发明涉及数字数据通信,并且提供了一种用于产生具有高度调制分集的数字数据调制的多维星座的有效方法,基于这样的星座发送和接收数据的方法以及相应的装置。 这通过仅考虑具有相同第一绝对值的对角线上的所有元素的多维旋转矩阵并且具有相同的非零第二绝对值的所有其它元素来实现。 以这种方式,可以生成仅具有单个独立参数和尽可能规则的结构的多维旋转矩阵。 可以配置独立参数以便最小化各种星座大小的误差概率。
