FREQUENCY ERROR CORRECTION FOR LTE UPLINK COMP |
摘要 |
A method includes, for a selected user equipment for signals corresponding in part to the selected user equipment and received by antennas from a number of cells, wherein each cell has one or more antennas, and wherein each signal is from an individual one of the antennas, performing the following: estimating carrier frequency offset for each cell using one or more of the signals from the cell; performing frequency offset correction on each signal from each cell by using at least the estimated carrier frequency offset for an associated cell; estimating a channel for each frequency offset corrected signal; and combining, using the estimated channels, each of the frequency offset corrected signals to generate one or more estimates of one or more symbols transmitted from the selected user equipment. A second frequency offset correction may be performed subsequent to the combining. Apparatus, computer programs, and software are also disclosed. |
