    摘要: In the novel method for data transmission via a radio interface in a radio communications system, at least two data channels are assigned to one connection. Each data channel can be distinguished by an individual spread code. In addition to data symbols, midambles with known symbols are transmitted in a data channel. The number of midambles being used for the connection is less than the number of data channels. The method is particularly suitable for use in TD/CDMA 3rd generation mobile radio networks.

    摘要: In a transmission method for simultaneous synchronous or asynchronous transmission of K data sequences consisting of data symbols, before transmission a specific signal form allocated to the data sequences is modulated on each of the data symbols of the K data sequences transmitted via a channel or K generally distinguishable channels, in order to generate the K transmission signals, which are all distorted by the one channel, or one of the K channels. In the receiver, continuous-valued provisional estimated values are calculated for some or all of the data symbols of the K input sequences according to a linear method, and a confidence level for the estimated values is calculated.

    摘要: A method is provided for transmitting information in a radio communication system provided with at least one transmitting station (AP) and at least two receiver stations (MT). The transmitting station (AP) and the receiver stations (MT) are connected together via a radio communication interface. The transmitting stations (AP) includes a transmitting antenna with K B 31 antenna elements, whereby K B ≧1, and the receiving stations (MT) respectively include a transmitting antenna with K M antenna elements, whereby K M ≧1, and which communicate via a MIMO-transmission. The transmitting signals transmitted from the antenna elements of the transmitting antenna of the transmitting station (AP) are produced in a common process and are adapted in relation to the transmitting energy to be used during radiation. Receiving signals received by the antenna elements of the receiver antenna of the receiver stations (MT) are detected in a linear signal process.

    摘要: In order to compatibly adapt a wireless telecommunication system with a CDMA, FDMA and TDMA multiple access component, particularly a hybrid “JD-CDMA” telecommunication system with respect to multiple access methods, to a GSM-specific/DECT-specific (micro-cell, macro-cell and/or Pico cell-specific) telecommunication system with respect to the air interface, signaling information fashioned as “stealing flag” for distinguishing between payload and signaling channels are first arranged such in a provided time slot structure that an asymmetrical division of the time slot data arises with respect to a training data block (midamble) of the time slot structure and, second, the transmission time duration for the provided time slot structure of a data element fashioned as “chip” and contained in the time slot structure is dimensioned such that this is a multiple of a predetermined clock frequency—for example, GSM/DECT-specific clock frequency—covering the numerical range from 5 through 7.

    摘要: A method for separating a signal mix composed of the additive superposition of M known functions that are weighted with M unknown weighting factors, whereby all or some of the functions are chronologically and/or spectrally not disjunctive. The signal mix including a potential noise signal is supplied to a signal evaluation device that, by filtering, forms true-to-expectation estimated values for the unknown weighting factors. For the first time, this provides a true-to-expectation separation of a signal mix composed of non-orthogonal functions. An apparatus for the implementation of the method forms linear combinations of the correlation products from the input signal and from the functions to be separated. Instead of the functions to be separated, versions of these functions modified according to the properties of the superimposed noise signal can also be used in the formation of the correlation products. An advantageous and cost-beneficial embodiment of the apparatus for separating the signal mix is an apparatus composed of M modified, signal-matched filters that are realized in analog or digital technology.
