    摘要: The propagation time for propagation of a radio signal from a radio transmitting station to a radio receiving station is estimated based on calculated correlation values, calculated energy values and a known energy value. The receiving station receives a series of received signals that respectively correspond to radio signaling bursts transmitted by the radio transmitting station. Each of the radio signaling bursts includes a known signaling sequence. The calculated correlation values are indicative of correlations between the received signals and the known sequence, the calculated energy values are calculated for the respective received signals, and the known energy value is the energy of the known sequence.

    摘要: In a mobile telecommunications network, a mobile station (MS) is configured to generate and uplink transmit position measuring data prior to and/or during a call connection, without noticeably interrupting the user or degrading the quality of service provided. Position measuring data can be uplink transmitted over an idle traffic channel during a call set up operation for a brief moment while the call connection is being completed. Position measuring data can also be uplink transmitted during a call by selectively stealing data positions or burst positions in the uplink signal. The position measuring data is received by a plurality of base stations and uplink signal characteristics are measured and collected. The measured uplink signal characteristic data from several base stations is then used to determine a current approximate geographical location of the mobile station.

    摘要: In locating the position of a radio transmitter in a radio communication network, signal timing measurements of a radio signal transmitted by the radio transmitter are obtained using respective satellite-based clocks. Clock discrepancy information about timing discrepancies between the satellite-based clocks is also obtained. The signal timing measurements are compared to obtain signal timing difference information, and the clock discrepancy information is used to eliminate effects of the timing discrepancies from the signal timing difference information.

    摘要: In systems which transmit both GSM modulated and EDGE modulated signals, time of arrival estimations can be improved without requiring the detection of the type of modulation used on the received signal. In accordance with the present invention, a received signal is initially demodulated by a receiver in accordance with a first demodulation scheme. The demodulated signal is split into two copies. Taking into account the initial demodulation, one of the copies is demodulated in accordance with another demodulation scheme, thereby resulting in a first signal demodulated in accordance with the first demodulation scheme and a second signal demodulated in accordance with a second demodulation scheme. A training sequence is used to correlate the two signals which are then summed in a incoherent integration process. The result of the incoherent integration is used to estimate the time of arrival of the received signal.

    摘要: A method for noise rise estimation in a wireless communication system comprises measuring (210) of received total wideband power of an antenna a plurality of times. An estimate of a noise floor measure is computed (212) based on at least a number of the measured received total wideband powers of the antenna. Interference whitening of a received signal is performed (214) per user for a multitude of users. A useful signal power per user after the interference whitening, preferably Frequency Domain Equalization, is determined (216). A noise rise measure per user is calculated (220), based at least on the useful signal power per user and the noise floor measure. The calculation in turn comprises compensation of the noise rise measure per user for the effects of the interference whitening. An arrangement for noise rise estimation is adapted for such a method. A radio base station comprises such an arrangement.
