摘要： A method and apparatus are disclosed for determining more accurately, in a radio environment with time dispersion, the distance between a radio receiver and radio transmitter, by special processing of received radio signals that have been transmitted repeatedly from the same radio transmitter and are possibly subject to multipath propagation. The Time of Arrival (TOA) of the received radio signals is repeatedly estimated using channel power profiles. A TOA value near the minimum occurring TOA is selected wherein each estimated TOA is derived from incoherent integration of a randomly chosen number of the received bursts having the same known bit sequence, in order to eliminate the influence of noise.

摘要： A method and system are disclosed for determining the distance between a radio receiver (RX) and a radio transmitter (TX) by uplink time measurements, whereby uplink messages are transmitted by the transmitter (TX) and used primarily for position determination. In one embodiment, the uplink messages are intra-cell handover messages if the transmitter (TX) is a component of a mobile radio terminal which is operating in accordance with an existing TDMA standard. In a second embodiment, the uplink messages are a new type of message transmitted in time slots not used by the mobile radio terminal and preferably, also not used by other mobile radio terminals in the system, if the transmitter (TX) is a component of a mobile radio terminal which is operating in accordance with a new or emerging TDMA standard. The evolving GSM radio air-interface standard is an example of such a TDMA standard.

摘要： The present invention discloses method and system for improving performance of interference cancellation in a radio communication system. The method comprises: estimating power of an interfering signal contained in a received signal; estimating power of an additive estimate error signal added to the interfering signal; and canceling the interfering signal from the received signal if the estimated power of the additive estimate error signal is lower than the estimated power of the interfering signal. A cellular mobile terminal and a cellular base station comprising the system are also disclosed.
