An LTE uplink soft demapper includes an SC-FDMA symbol noise power meter (22) configured to individually determine a noise power measure for each SC- FDMA symbol in a slot by exploiting information contained in modulated data symbols of the corresponding SC-FDMA symbol. A bit soft value normalizer (24) connected to the SC-FDMA symbol noise power meter (22) is configured to normalize bit soft values, representing reliability of received bits obtained from the SC-FDMA symbols in the slot, based on the determined noise power measures. |
