摘要： Error vector magnitude (EVM) is pooled and adaptively distributed among carriers in a multi-standard or multi-carrier system to reduce peak to average power ratios (PAPR) without exceeding EVM limits. Correction tone injection is used to reduce PAPR. The amplitude of each correction tone, and number of correction tones assigned to a carrier, are adjusted to control the EVM and out-of-band distortion of each carrier, to comply with EVM limits imposed by the respective radio access technology.

摘要： A method for dynamically adapting the maximum output power of a femto base station is provided. The method is based on determining the number of satellites currently detected and/or the reception quality of the satellite(s), and dynamically adapting the maximum output power from the femto base station in response to the determined number of satellites and/or the reception quality of the satellite(s). Hereby, an accurate position of the femto base station can be obtained for providing input used for determining the maximum output.

摘要： A wireless receiver utilizes a single analog oscillator (40) to down-convert (24, 34) multi-carrier signals in one or more receiver front-end paths (22, 24, 26, 32, 34, 36). The received signals are digitized (28, 38), and the different carrier signals received at each antenna (22, 32) are separated in digital domain (42) by mixing the digitized signal from each antenna with a carrier/antenna separation digital oscillator to down-convert a desired carrier signal and low-pass filtering to remove unwanted carriers. A coarse frequency correction (56) adjusts the analog oscillator (40), and fine frequency corrections (58) adjust digital oscillators mixing with the separated signals. In one embodiment, the fine frequency correction is applied to the carrier/antenna separation digital oscillators in the separation function (42). In another embodiment, the fine frequency correction is applied to frequency adjustment digital oscillators mixing with the separated signals. The frequency corrections may be based on reference symbols in the received signals.

摘要： The present invention relates to a method for sending reserved sub-carriers to a UE for the purpose of reducing peak to average power ratio (PAPR) of the transmitted signal to ensure sufficient quality of the modulated signal to achieve high data rate, including the steps of sending the information related to dynamic activation and deactivation of reserved sub-carriers on a common channel, which is readable for all UEs in idle and in connected mode; dynamically activating the transmission of the reserved sub- carriers in a cell when high modulation quality is to be maintained; dynamically deactivating the transmission of the reserved sub-carriers in a cell when high modulation quality is not required. The invention furthermore relates to a radio base station and a UE relating to said method.
