摘要： The propagation time for propagation of a radio signal (93) from a radio transmitting station to a radio receiving station (91) is estimated based on calculated correlation values (102), calculated energy values (101) and a known energy value. The receiving station (91) receives a series of received signals (93) 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 (102) are indicative of correlations between the received signals and the known sequence, the calculated energy values (101) are calculated for the respective received signals, and the known energy value is the energy of the known sequence.

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.

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 an incoherent integration process. The result of the incoherent integration is used to estimate the time of arrival of the received signal.

摘要： A mobile communication station in (MS1) a wireless communication network is used to measure the respective times of arrival of radio signals respectively transmitted by a plurality of radio transmitters (23, 28) in the network. The mobile communication station is provided with real time difference information indicative (RTDs) of differences between a time base (60) used by a radio transmitter (23) serving the mobile communication station and respective time bases used by the other radio transmitters. The mobile communication station determines, in response to the real time difference information and relative to the time base used by the radio transmittter serving the mobile communication station, a plurality of points in time at which the respective radio signals are expected to arrive at the mobile communication station. For each radio signal, the mobile communication station monitors for arrival of the radio signal during a period of time after the point in time at which the radio signal is expected to arrive.

摘要： A recursive method (100) of calculating an inverse impairments matrix is used to generate an SINR estimate, which in turn is used to generate a CQI estimate. The recursive inverse impairments matrix calculation avoids the need to perform a computationally intensiv matrix inversion, allowing for faster CQI estimate generation and consuming less power.
