20100303166 | Apparatus and Method for Inserting a Cyclic Postfix for a Time-Rotated Symbol in a Communication System - An apparatus and method for inserting a cyclic postfix for a time-rotated symbol in a communication system. In one embodiment, the apparatus includes a time pre-rotation module configured to time shift bits of at least one of ending samples of a symbol to a beginning of the symbol to form a time-rotated symbol. The apparatus also includes an interpolator configured to construct an up-sampled symbol from the time-rotated symbol and a cyclic postfix module configured to insert a cyclic postfix at an end of the up-sampled symbol to form an expanded up-sampled symbol. | 12-02-2010 |
20110143770 | METHOD AND APPARATUS FOR ESTIMATING A POSITION OF A NODE IN A COMMUNICATIONS NETWORK - A method and apparatus are provided for timed estimation-based positioning of a user equipment in LTE systems. The method includes estimating, by a mobile node, a plurality of reference signal time differences (RSTD) between the mobile node and a network node. The plurality of RSTD estimates define a first correlator. The method further includes determining a second correlator of RSTD estimates, and defining the second correlator with the first correlator based on a mean of the plurality of RSTD estimates. Further, the method includes determining a distribution of the plurality of RSTD estimates, and grouping clusters of RSTD estimates in the distribution. Additionally, the method includes selecting a cluster from the clusters of RSTD estimates. The cluster includes RSTD estimates closest to a center of the second correlator. The cluster is transmitted, by the mobile node, to the network node for positioning the mobile node in a communications network. | 06-16-2011 |
