Abstract: An apparatus for controlling a photogrammetrical camera includes a frosted glass adjacent to which or in an optically conjugate plane thereto a transparent planoparallel sheet of voltage sensitive material is arranged. Spaced electrodes are allocated to the one face of said sheet and a sheet electrode to the other face. Each of the spaced electrodes is connected to respective outputs of an electronic counter, which in dependence of a tunable pulse generator applies voltage pulses to the spaced electrodes and the sheet electrode, both sandwiching said sheet of voltage sensitive material and rendering visible the inbetween portions of said material when submitted to a potential so that lines or a cyclic pattern of lines appear. The voltage sensitive material can be liquid or gaseous or solid and can be sandwiched between two substantially plano-parallel plates which have the respective electrodes or electrode on their inner faces.

Abstract: The present invention provides a method and an apparatus for measuring a reception quality on a wireless communication link to a receiver by removing a bias in a plurality of received pilot symbols and obtaining a channel estimate for a channel, such as a wireless propagation channel, after substantially removing the bias. For a receiver, such as a rake receiver disposed in a base transceiver station, a bias removal module may extract a plurality of coefficients from a wireless propagation channel to remove a bias before a detector may receive the plurality of pilot symbols in the data stream to determine an error rate of the received pilot symbols where channel estimation is based on the received pilot symbols. In this manner, a systematic flaw in a link quality measurement based on an error rate of the received pilot symbols may be resolved for wireless communication systems.

Abstract: The invention relates to a method and a device for processing signals of a digital transmission system in general, and for estimating the frequency offset of the transmission system in particular. In one embodiment, the method according to the invention estimates the pulse response of the transmission system and shortens the pulse response by means of a variable prefilter. The duration of the shortened pulse response is, in particular, shorter than the duration of a known symbol sequence which is transmitted twice identically within one method cycle. By comparing samples of the received signal which correspond to the known identical symbols, the frequency offset is estimated reliably, and suitable measures can be taken to compensate it. Consequently, the efficiency of the receiver is substantially improved with respect to the recovery of the transmitted data. The invention can be used, in particular, for transmitting data in blocks, even when there is no freedom from inter-symbol interference, and even when the unshortened pulse response is longer than the known symbol sequence. Transmission using GSM/EDGE systems is one field of application.
Abstract translation: 本发明一般涉及用于处理数字传输系统的信号的方法和装置，并且用于特别地估计传输系统的频率偏移。 在一个实施例中，根据本发明的方法估计传输系统的脉冲响应并且通过可变预滤器缩短脉冲响应。 缩短的脉冲响应的持续时间特别地短于在一个方法周期内两次相同传输的已知符号序列的持续时间。 通过比较对应于已知相同符号的接收信号的样本，可靠地估计频率偏移，并且可以采取适当的措施来对其进行补偿。 因此，相对于传输数据的恢复，接收机的效率显着提高。 即使当不存在符号间干扰的自由时，甚至当未通知的脉冲响应比已知符号序列长时，本发明也可以特别地用于以块传输数据。 使用GSM / EDGE系统的传输是一个应用领域。

Abstract: Improved frequency utilization in a radio network is achieved by using a radio system with a plurality of base stations, which respectively have at least one transmitter and one receiver, each base station being assigned at least one dual-polarized antenna. More efficient utilization of the available frequency band, and consequently a reduction in the cluster size, is made possible by the dual-polarized antenna being assigned a polarization modulator for changing at predetermined points in time the polarization state of a transmit signal to be transmitted.
