  • Patent number: 6643518
    Abstract: For synchronous transmission between two telecommunications units, the devices must always be synchronized. Typically, a reference signal is required for synchronization. The reference signal can be transmitted from one unit to another embedded in the data signal. If the data is transmitted via a transmission network modulated in the way required by the network, the reference signal is not always received by the receiver together with the data signal. The problem is solved by this invention by converting the reference signal before its transmission into the transmission network for the frequency band used for transmission in the transmission network.

  • Patent number: 6104936
    Abstract: In a cellular telecommunications network, uplink interference, as measured by a base station in a target cell, and co-channel interference, as measured by mobile units in a co-channel cell are reduced by increasing the base station antenna tilt angle. However, increasing the base station antenna tilt angle reduces the effective coverage area of the target cell. To obtain an optimum base station antenna tilt angle, interference reduction and target cell coverage area reduction are quantified for each of a number of candidate base station antenna tilt angles. An interference reduction-to-target cell coverage area reduction ratio can then be established for each of the candidate base station antenna tilt angles. The optimum base station antenna tilt angle can then be identified as the one candidate base station antenna tilt angle that reflects the maximum interference reduction-to-target cell coverage area reduction ratio.

  • Patent number: 6070091
    Abstract: A method of detecting the degradation of a transceiver performance due to intermodulation products in radio base stations is disclosed. In an embodiment of the invention, the method includes measuring the received signal strength for each individual receiver frequency and recording the operational state of all transmitters. A plurality of data samples are used to determine a correlation between the received frequencies and associated disturbance. The degradation of signal reception caused by intermodulation (IM) products is derived from the correlated samples. If the performance is found to be below a predetermined value, a notification is initiated upon which corrective action can be taken. The method provides for prompt indication of poorly performing transceivers due to interference from IM products.

  • Patent number: 5987320
    Abstract: An quality testing apparatus and method for providing an objective and real-time evaluation of voice quality in a wireless communication system. The system under evaluation would include a receiving and transmitting apparatus at both ends of the system. To evaluate voice quality, one apparatus transmits a TDM base band voice test signal to a receiving apparatus. The configuration of the transmitted TDM base band voice test signal permits the receiving end to synchronize a test sentence, contained within the TDM test signal, with a corresponding reference sentence stored at the receiving apparatus. After synchronization, the receiving apparatus uses a model of human hearing to objectively compare the two sentences, and based on the result, outputs an AQS ranking. In addition to voice quality, the apparatus measures SINAD, noise, distortion, and signal level of transmitted test tones and maintains a log of call progress statistics.
