Abstract: In a radio communication system, a beam is formed between subscriber stations and a base station which has an antenna device with several antenna elements. The antenna elements emit a downlink signal based on respective weighing with coefficients of a weighting vector. A plurality of weighting vectors are determined at the subscriber station in an initialization phase and transmitted to the base station. In a subsequent working phase, the subscriber station selects a dominant weighting vector from the weighting vectors and transmits a designation of the selected weighting vector to the base station.

Abstract: A receiver that operates to recover data from spread spectrum radio signals, which include radio signals generated from a combination of the data and a data spreading code associated with the user and radio signals generated from a combination of a predetermined sequence of pilot data and a pilot spreading code. The receiver includes a plurality of antennas, each arranged to detect a different version of the radio signals. Base band conversion means is coupled to the plurality of antennas and arranged to generate, for each antenna, base band signal samples representative of the version of the radio signals. Data recovery means operates to correlate each version of the signal samples with respect to the pilot spreading code, form at least one covariance matrix from a frequency domain representation of a predetermined temporal window of the correlated pilot signals samples, correlate each version of the signal samples with respect to the user data spreading code, form a frequency domain representation of each version of the data correlated signal samples, and detect the data from the frequency domain data correlated signal samples in combination with the at least one covariance matrix. A method used with the receiver is also provided.

Abstract: Signals in the form of wave elements of one or more subscriber signals are received at a receiving device assigned a number Ka of receiving sensors and the direction of the signals is estimated. Ka received signals are received via the receiving sensors and are composed of at least one subscriber signal which has a transmitter-specific fine structure impressed on it. A kth subscriber signal, with k=1 . . . K, is transmitted by means of Kd wave elements whose directions of arrival at the receiving location differ. Channel impulse responses assigned to the Ka receiving sensors are determined from the received signals, and the direction of arrival of at least one wave element is determined from the channel impulse responses. The direction estimation can advantageously be used in mobile radio, radar, sonar or seismic measurement systems.

Abstract: Drug screening assays useful in the discovery of pharmaceutically active compounds for use in the treatment of diseases involving abnormal lipid metabolism including diabetic neuropathy are taught. In particular, the control region of delta-5-desaturase gene is taught as a target for the drug screening methods, which serve to identify nucleotides, proteins, compounds and/or other pharmacological agents, which modulate the activity of desaturase enzymes or regulate the level of expression of the desaturase genes. Cell-based and cell lysate assays are taught for detecting components that interact with the desaturase enzymes and modify fatty acid profiles. In addition, cell-based and cell lysate assays are used to identify functional and regulatory elements controlling expression of the desaturase genes as well as to screen for components that modulate the transcriptional activity of the desaturase genes. Also taught is the gene for rat delta-5-desaturase.

Abstract: A method for measuring characteristics of radio channels, in which the signals are received by a total of M1 receiving sensors in a linear antenna array, in which case the respective received signals are composed of wave elements of a transmitted signal with a different incidence direction and different delay, the transmitted signal contains a preselected test sequence, and the incidence angle as well as the delay of the dominant wave fronts are estimated simultaneously, taking account of the chip signal form of the test sequence, the signals from each antenna sensor are demodulated, and sampling is then carried out with Mc samples per chip in the test sequence. In this case, the resultant Nc×Mc samples are transformed to the frequency domain by discrete Fourier transformation, and the values which are obtained from this are corrected taking account the spectrum of the chip signal form, in which case the line vectors formed from the values obtained for each sensor can be combined to form a data matrix XF′(n), which contains invariances which characterize the channel.

Abstract: A method for allocating radio channels in a radio communications system having timeslots includes the steps of allocating the radio channel for the downlink direction to a mobile station as a function of a channel allocation pattern which indicates the transmission power levels for the timeslots. The mobile station corrects the allocation of the radio channel as a function of an interference pattern which indicates the interference power levels in the timeslots. The allocation process results in the transmission power level being distributed as uniformly as possible between the timeslots which are provided for a connection from the radio station in the downlink direction, wherein the allocation process is a function of the occupancy of the timeslots in accordance with the channel allocation pattern. The ability of correcting the allocated timeslot under the control of the mobile station allows to avoid a disadvantageous soft handover, even with a frequency repetition interval equal to unity which is critical with respect to interference.

Abstract: Space covariance matrices are first defined for a kth link from the base station to a wireless station and for a sum of further radio stations, that is to say, in the latter case, the interference for the kth link. In a second step, a beam forming vector w(k) is calculated for the link such that the signal-to-noise ratio in the receiver is maximized. A general intrinsic value problem is thereby solved without iterations. Transmission signals are then weighted with the beam forming vector for the link, and are supplied to the antenna elements for transmission. The method is suitable for TDMA/CDMA and CDMA transmission methods using smart antennas.

Abstract: The characteristics of radio channels are measured. The signals received by a plurality Mc of receiving sensors of a two-dimensional antenna array are composed of wave elements of a transmission signal with regard to the azimuth and the elevation of a different two-dimensional incidence direction and different delay. The transmission signal contains a preselected test sequence, and the incidence angle as well as the delay of the dominant wave fronts are estimated simultaneously taking account of the chip signal form of the test sequence. The signals of each antenna sensor are demodulated, and sampling is then carried out with Mc samples per chip in the test sequence. The resultant samples are transformed to the frequency domain by discrete Fourier transformation, and the resultant values are corrected taking account of the spectrum of the chip signal form, wherein the line vectors formed from the values obtained for each sensor can be combined to form a data matrix XF, which contains invariances that characterize the channel in the space/frequency domain.
