Patent number: 8275023Abstract: Signal impairment correlations for multiple signals in a received multipath signal are constructed by fitting parametric models associated with each high-data-rate signal in the multipath against measured impairment correlations. The estimated model fitting parameters are applied to form impairment correlation estimates for all signals. The models comprise a separate impairment covariance matrix scaled by a model fitting parameter for each high-data-rate signal and a noise covariance matrix scaled by a noise element model fitting parameter. The model fitting parameters may be estimated by a least-squares formulation and applied to form impairment correlation estimates for all signals of interest. The resulting impairment correlation estimates may be provided to G-RAKE receivers or joint scaling demodulators to demodulate the signals while suppressing interference from the high-data-rate signals.Type: GrantFiled: December 12, 2006Date of Patent: September 25, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Yi-Pin Eric Wang, Carmela Cozzo, Gregory E.

Patent number: 7848743Abstract: An inherent non-observability of the thermal noise power level is circumvented by estimating an upper limit of the thermal noise power level by time evaluations. An instantaneous total received wideband power is measured in a receiver. Preferably, also an instantaneous sum of powers of all links used in the same cell is provided. A quantity (P?), preferably the difference between the instantaneous total received wideband power and the instantaneous sum of powers of all links used in the same cell, is followed (110) during a time period (TLag). A minimum value (PMIN) of that quantity is then used as an estimate of the thermal noise power level upper limit. Preferably, the time period is configured as a sliding window. An improved determination of noise rise can then be calculated and used for controlling traffic within the cell.Type: GrantFiled: June 8, 2005Date of Patent: December 7, 2010Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Torbjorn Wigren, Gunnar Peters, Leif Thomas Ostman
